Find the area of the triangle formed by the points `A(0, – 1), B(– 2, 6) ` and `C(– 3, – 5) `

Answer

D

Explanation

Graph of `y = sin^(-1) (sin x) and y = x//4` intersect at three points. So, number of solution is 3

(b) Graph of `y = cos^(-1) (cos x) and y = x//4` interect at four points. So, number of solution is 4.

(c) Graph of `y = tan^(-1) (tan x) and y = x//4` interect at three point. So, number of solution is 3.

(d) Graph of `y = cot^(-1) (cot x) and y = x//4` intersect at two points. So, number of solution is 2.
