Question

(Tan theta + sec theta -1) ( Tan theta + sec theta -1) = 2sin theta / 1- sin theta

Answer 1

Step-by-step explanation:

4e_{3} * h ^ 3 = (e ^ 3 + e ^ - 1)/2

Log (tot [II + 6)

tosha e ing (cot /# +o) -log (cxt| [[+0]) te

cot (ute) - kan ( Ito)

2

cas ² (m/u+o) + sin² [1/4 +0) 2 sin ( 17/4 to) cos(Mutes)

sin 2/17uta)

sin / 1/2 sin/17/22 +20)

Cos 20
