Question 10: Find the principal value of cosec¯¹(√2)

Class 12 - Math - Inverse Trigonometric Functions

Answer 1

$\textbf{HelloMate}$

$\textbf{Your Answer}$>>>

Let y = $\upper{cosec}^{-1}$(√2)

cosec y = √2

we know that the value √2 lies at cosec(45)

so we can write cosec(45) as cosec($\frac{π}{4}$)

cosec y = cosec($\frac{π}{4}$)

cosec and cosec cancelled out

so we get>>>>

y = $\frac{π}{4}$
