There are four basic conversion formulas in trigonometry to transform sine function as cosine function and vice versa Sine to Cosine Transformation Basically there are two ways to convert sine function in terms of cosine function 1 sin 2 1 cos 2 Sine Cosine and Tangent are the main functions used in Trigonometry and are based on a Right Angled Triangle Before getting stuck into the functions it helps to give a name to each side of a right triangle Opposite is opposite to the angle Adjacent is adjacent to next to the angle Hypotenuse is the long one
The general equation for a sine and cosine curve is y Asin x h k and y Acos x h k respectively Similar to other function transformations h is the horizontal shift also called a phase shift and k is the vertical shift Then cos cos and sin sin where the choice of the depends on the quadrant in which the terminal side of lies Howto Use reference angles to find the sine or cosine of an angle Measure the angle between the terminal side of the given angle and the horizontal axis

We then define the cosine and sine of the arc t as the x and y coordinates of the point P so that P t cos t sin t we abbreviate the cosine as cos and the sine as sin So the cosine and sine values are determined by the arc t Learn how to find the sine cosine and tangent of angles in right triangles The ratios of the sides of a right triangle are called trigonometric ratios Three common trigonometric ratios are the sine sin cosine cos and tangent tan These are defined for acute angle A
