Question

tan 2 theta + cot2 theta = sec2 theta * cosec2.theta-2​

Answer 1

Answer:

sec2 theta-1+cosec² theta-1= (tan² theta=sec² theta-1)

sec²×cosec2 theta

sec² theta+cosec2 theta-2=sec² theta×cosec2 theta-2

sec² theta+cosec² theta-2+2=sec² theta×cosec² theta

1/cos² theta+1/sin² theta=sec² theta×cosec² theta.

sin²theta+cos²theta/sin²×cos²theta=sec²theta×cosec² theta

1/sin² theta×cos2 theta.

sec²theta×cosec² theta=sec2 theta×cosec2 theta.
