Question

if tan 45 = 1 find all the trigonometric ratio​

Answer 1

Answer:

sin 45 is 1/root 2 ,cos 45 is 1/root 2 ,sec is root2 ,cosec is root 2 and cot 45 is 1

Answer 2

Answer:

Now, ∠OPQ = 180° - ∠POQ - ∠PQO

= 180° - 45° - 90°

= 45°.

Therefore, in the △OPQ we have, ∠QOP = ∠OPQ.

Therefore, PQ = OQ = a (say).

Now,

OP2 = OQ2 + PQ2

OP2 = a2 + a2

OP2 = 2a2
