Question

Equation of the image of the line x + y = sin^–1(a³ + 1) + cos^–1(a² + 1) – tan^–1(a + 1), a Ī R about y-axis is given by

• A. x – y + $\frac { \pi } { 4 }$ = 0
• B. x – y = 0
• C. x – y = $\frac { \pi } { 4 }$
• D. x – y = $\frac { \pi } { 2 }$

Answer 1

Answer: (A)

x – y + $\frac { \pi } { 4 }$ = 0

Answer 2

a = 0

equation x + y = $\frac { \pi } { 2 }$ – $\frac { \pi } { 4 }$

image x – y + $\frac { \pi } { 4 }$ = 0
