Question

if root 2 sin thita =1 find value of sec square thita - cos square thita

Answer 1

Step-by-step explanation:

√2 sin theta = 1

if we put theta = 45°

f we put theta = 45°we'll get answer as 1

f we put theta = 45°we'll get answer as 1just for sake I'll verify it for u!

f we put theta = 45°we'll get answer as 1just for sake I'll verify it for u! (√2×1/√2 = 1)

So putting same value=>

Q= sec^2 theta - cos^2 theta

=1/cos^2theta - cos^2theta

=√2 - 1/√2

= 2-1/√2

= 1/√2

Hope it helps you buddy!

Answer 2

Answer is 3/2
