Frequently Asked Questions

First, isolate the trigonometric function. Then, use the cofunction identities (sin(cosine(x)) = tan(x) or cos(sin(x)) = sec(x)) to rewrite the equation. Solve for x in the range 0 to 2π.
Use the tangent sum identity: tan(x + y) = (tan(x) + tan(y)) / (1 - tan(x)tan(y)). Then, simplify the expression.
The fundamental period of the function y = sin(3x) is 2π/3. This is because the coefficient of x in the sine function determines the period.
To find the inverse of a trigonometric function, swap x and y, then solve for the new y. For example, to find the inverse of sin(x), swap x and y to get y = sin(x), then solve for y to get arcsin(x).
