Question

cot square x + tan square x =?​

Answer 1

Given-

cot square x = tan square x

To fine-

value of x

Solution-

Step 1

For solving the above question one of the term needs to be common. So, we write it as

cos square x / sin square x + sin square s/cos square x

as we know tan square x = sin square x/cos square x

                     cot square x = cos square x/sin square x

Step 2

take out LCM of both the terms

cos4 x + sin4 x/ sin square x cos square x

Step 3

apply formula

1+1/1/4sin square (2x)

Step4

4 becomes the whole of both terms

2/sin square (2x)
