Question

prove that
sin*2 270 + 3 tan 360° - 2sec 180=3.​

Answer 1

Answer:

Step-by-step explanation:

Here Some Trigonometry Value are given below

$\sin 270 = - 1 ; \tan 360 = 0 ; \sec 180 = - 1$

From L.H. S

$\sin ^{2}(270) + 3 \tan (360) - 2 \sec (180)$

( - 1)²  + 3 × 0 - 2 × ( -1)

1 +0 +2

=  3 R.H.S
