Question 2 of 60
Q 2. For all o, sin 0 + sin(-0) + cos 0 + cos(-0) + tan 0 + tan(-0) = ?
Oa) 2 sin e
Ob) 2 cos e
(c) 2 tan 0
Od) 2 sin o tan 0​

Answer 1

Step-by-step explanation:

OP makes an angle θ with the positive direction of x-axis

and OQ makes an angle (α−θ) with the positive direction of x-axis.(Fig)

So that ∠POQ=α and thus Q is obtained from P by clockwise rotation through an angle α around the origin

Note:In the anticlockwise rotation, OQmakes (2π−α+θ) with the +ve direction of x-axis.
