Question

(1-sin^theta)sec^theta=1​

Answer 1

Answer:

(1 - sin2 theta) sec2 theta = 1

as we know that sin2 theta + cos2 theta = 1

therefore cos2 theta = 1 - sin2 theta

cos2 theta × sec2 theta = 1

as sec2 theta = 1/cos2 theta

cos2 theta × 1/cos2 theta = 1

1 = 1

LHS is equal to RHS

hence proved

Answer 2

Step-by-step explanation:

(1-sin²ø)sec²ø

=cos²øsec²ø

=(cos øsecø)²

=1²=1.(proved)
