Question

if √2 sin theta=1 Find sec²theta-Cosec²theta​

Answer 1

Answer:

✓2sinthetha = 1 then ,

sintheetha=1/✓2

theetha equal to=45

sec^245-cosec^245 =1/2-1/2=0

Answer 2

Answer:

√2sin theta=1

sin theta=1/√2=sin 45°

so, theta=45°

sec^2theta-cosec^2theta

=sec^2 45°-cosec^2 45°

=(√2)^2-(√2)^2

=2-2

=0
