Sin and cos calculator

Algebrator math calculator has been helping high-school and college students conquer math for more than three decades. Unlike other free math apps, our algebra calculator shows you all steps of the solution as well as explanations to any math textbook problem you enter. This calculator app solves math homework problems just like your teacher! Explanations will tell you not only which algebra rule is being used, but also how it is applied in your particular math problem. Your math homework will be done fast!Fraction calculator will show steps to add, subtract and multiply fractions, as well as complex fraction division. After reducing fractions or rational numbers to simplest terms, fraction to decimal calculator will assist you with converting fractions to percentages. Lowest common denominator (lcm, lcd) calculator will help make equivalent fractions. Simplifying fractions also includes rationalizing denominators and numerators.Graphing calculator will graph lines, horizontal and vertical asymptotes, x and y intercepts. It will produce graphs of quadratic equations, functions and parabola equations, linear equations (lines) and inequalities, trig. functions (e.g. cos graph) and curves such as hyperbola and circle equations. The graphing calculator math app will also show fractions on the number line, find the slope of a line as well as a parabola vertex. After placing polynomials in standard form, it will graph any polynomial function. Many other functions such as logarithmic, exponential and absolute value can also be graphed.Equations and inequalities found in your math homework assignments can be solved by several math equation solvers (e.g. quadratic equation calculator, linear equations calculator and system of equations solver (solving by substitution and addition)). Quadratic formula calculator will put a quadratic equation in standard form and then either use quadratic formula or solve by factoring. Logarithmic, rational, exponential, linear and quadratic equation solver will solve for x or any other math variable. Systems of linear equations and inequalities will be graphed to produce visually appealing math solution. Linear inequalities, polynomial equations, absolute value equations and inequalities are all solved by our algebra solver that shows work just like your teacher.Factoring calculator can factor polynomials, trinomials and binomials. It will also factor quadratic equation so that it can be solved by the equation solver. Many different factoring methods such as factoring by grouping, difference of two squares, difference of two cubes, sum of two cubes are used. Greatest Common Factor or GCF calculator and perfect square trinomials are also used in the polynomial factoring calculator.Trigonometry calculator simplifies algebraic expressions with trig functions (such as sin x, cos x). It knows special values on trig unit circle (e.g. cos 0, sin 0, cos 1, sin 1, cos 30, sin 30, cos 45, sin 45, cos 60, sin 60, cos 90, sin

Scientific Calculator Created Using Visual BasicThis is a calculator that resembles a typical scientific calculator , albeit a simpler version. In our version, we have only included the trigonometric functions and the logarithmic functions. The reason of creating a simpler version of the calculator is to help users to learn the programming concepts in a gradual manner and not to confuse them especially those who are learning to program in Visual Basic.To design the interface, we just to need to modify the interface of the basic calculator that we have created earlier using Visual Basic 6. In this calculator, we have added five more buttons, they are Sin, Cos, Tan, Log and Ln. The common trigonometric functions in Visual Basic 6 are Sin, Cos, Tan and Atn.a) Sin is the function that computes the value of sine of an angle in radian.b) Cos is the function that computes the value of cosine of an angle in radian.c) Tan is the function that computes the value of tangent of an angle in radian.d) Atn is the function that computes the value of arc tangent of an angle in radian.Log computes the value of logarithm to base 10 whilst Ln computes the value of natural logarithm.An angle in degree has to be converted to radian before it can be calculated by the above trigonometric functions. From high school mathematics, we know that π radian is equivalent to 180°; which means 1 radian is equivalent to π divided by 180. Therefore, in order
