Question

find the value of 4 by 3 tan square 30 + sin square 60 - 3 cos square 60 + 3 by 4 x square 60 - 2 x squared 45

Answer 1

Answer:2

Step-by-step explanation:

"So here is how you can find the value of 4 by 3 tan square 30 + sin square 60 minus 3 cos square 60 + 3 by 4 x + 60 - 2 tan 45 degree

=>sin 30°=1/2

=>sin^2 30°=1/4

=>cos 45°=1/root 2

=>cos^2 45°=1/2

=>tan 60°=root 3

=>tan ^2 60°=3

So,2sin^230°-3cos^245°+tan^2 60°

=>2(1/4)-3(1/2)+3

=>1/2-3/2+3

=>(1-3+6)/2

=>4/2

=>2
