Question

4 tan^2 30 +2 cos^90+1/2 sin^2 90+sin^30cos^2 45-23/45

Answer 1

Answer:

Step-by-step ex

( I doubt you can use any identities)(Stick to their values)

tan 30 degree = 1/root3

cos 90 degree = 0

sin 90 degree = 1

cos 45 = 1/ root 2

NOTE: cos^2 45 degree is the same as (cos 45 degree)^2 (It is also a sub note in NCERT)
