Question

If tan theta + cot theta is equals to 7 then find the value of tan square theta + cot square theta

Answer 1

hence it is given that

tan theta + cot theta = 7

by squaring both side we obtain

(tan theta + cot theta)^2 = 7^2

tan ^2 theta + cot ^2 theta + 2 tan theta × cot theta = 49 (by the formula of (a+b)^2)

tan tan ^2 theta + cot ^2 theta +2= 49 (tan theta × cot theta = 1)

tan tan ^2 theta + cot ^2 theta = 49-2= 47
