Chapter 7: Q.4 (page 473)

$\tan^{2} (θ) - \sec^{2} (θ)$

Short Answer

Expert verified

The answer of $\tan^{2} (θ) - \sec^{2} (θ) i s - 1$

Step by step solution

01

Given information

We are given an equation $\tan^{2} (θ) - \sec^{2} (θ)$

02

We use trigonometric identity to solve

We have,

$1 + \tan^{2} (θ) = \sec^{2} (θ) \tan^{2} (θ) - \sec^{2} (θ) = - 1$

03

Conclusion

The value of $\tan^{2} (θ) - \sec^{2} (θ) i s - 1$ .

Show that $c o t^{- 1} e^{v} = \tan^{- 1} e^{- v}$

Express the product $\sin (3 θ) \sin (5 θ)$ as a sum containing only sines or only cosines.

In Problems 9–36, find the exact value of each expression.

$\tan [\cos^{- 1} (- \frac{\sqrt{3}}{2})]$

$\cos (2 θ) = \cos^{2} θ -$ $=$ $- 1 = 1 -$ .

Establish each identity.

$\frac{s e c^{2} v - \tan^{2} v + \tan v}{s e c v} = \sin v + \cos v$
