Question

secant theta is equals to 6 and tan theta is equal to 6 by x then find the value of 9 into x square minus one by x square​

Answer 1

Answer:

So, sin x/ cos x = cos x

sin x = cos ^2 x

Squaring,

sin^2 x is cos^4 x

Add cos^2 x on both sides,

1 = cos^4 x + cos ^2 x

Use quadratic formula

So, cos x is found..

Hence, sec x will be

\sqrt{2 \div (1 +   \sqrt{5)} }
