## Important Topics for SL Loney Plane Trigonometry Solutions Chapter 18: Inverse Circular Functions.

The Inverse Circular Functions in trigonometry is written as sin-1x, cos-1x, cot-1 x, tan-1 x, cosec-1 x, sec-1 x. There are several functions of these functions.

The Inverse Circular Functions is used for obtaining the angle of a circle from any of the trigonometric functions. If the function y=f(X) and x= g(y) then the inverse function is g= f-1.This implies when y=f(x) then x= f-1(Y)

Some of the important formulas are

1. sin-1 (-x) = -sin-1(x), x ∈ [-1, 1]
2. cos-1 (-x) = π -cos-1(x), x ∈ [-1, 1]
3. tan-1 (-x) = -tan-1(x), x ∈ R
4. tan-1(-x) = -tan-1(x), x ∈ R
5. cosec-1(-x) = -cosec-1(x), |x| ≥ 1
6. sin-1(1/x) = cosec-1(x), if x ≥ 1 or x ≤ -1
7. cos-1(1/x) = sec-1(x), if x ≥ 1 or x ≤ -1
• The inverse formulas help in solving problems reliably by applying all properties to get the solutions. To prove certain statements or get the value of the angles, some of the inverse formulas in trigonometry is of great help.
