Free trigonometric equation calculator - solve trigonometric equations step-by-step This website uses cookies to ensure you get the best experience. In the examples which follow a number of angles and their trigonometric ratios are used frequently. Such as solving trig equations multiple angles using only the mathematics on tests and cosine which the parentheses.
Solving Trigonometric Equations with Multiple Angles When confronted with trigonometric equations that have a multiple angle such as sin2x or cos3x recall that ysinBx is a horizontal compression by a factor of B of the function ysin x. Left sin x right 2 cdot left left cot x right 2 1 right sinx2 cotx2 1 cos pi cosπ tan x tanx cos 3x pi 05. Equations with multiple angles in a given range care must be taken not to fall into common mistakes.
Multiple-angle trigonometry expressions are those where the angle measure is some multiple of a variable for example 2 x or 3 y. Since I dont know how to format on here let x_1 be read as x sub 1 similarly let x_2 be read as x sub 2. Sinθ Tanθ and 1 are the heights to the line starting from the x-axis while Cosθ 1 and Cotθ are lengths along the x-axis starting from the origin.
