Answer 1

Step-by-step explanation:

hope it is helpful to you

Answer 2

Answer:

We know that,

cos 30 degree = root 3 / 2

sin 45 degree = 1 / root 2

cos 90 degree = 0

Therefore,

cos^2 30 degree . sin^4 45 degree . cos 90 degree = (root 3 / 2)^2 * (1 / root 2 )^4 *0

                                                                                       =0

THEREFORE THE REQUIRED ANSWER IS ZERO
