A

(a)tan⁡−1(34)\tan^{- 1}\left( \frac{3}{4} \right)

A

(b)tan⁡−1(43)\tan^{- 1}\left( \frac{4}{3} \right)

A

(c)sin⁡−1(34)\sin^{- 1}\left( \frac{3}{4} \right)

A

(d)cos⁡−1(43)\cos^{- 1}\left( \frac{4}{3} \right)

Explanation

Solution

(b)

tan–1 (AxAy)\left( \frac{A_{x}}{A_{y}} \right) = angle with y-axis.
