Question

1. If 7 cosec 0-3cotA=7 then prove that 7cot 0-3cosec 0 = 3.​

Answer 1

Answer:

3(when angle 90°)

Step-by-step explanation:

Now, 7 cot0-3cosec0 =3

Because angle is 90° then,

Cot 90° = 0

Now, cosec 90° = 1

Then, 7 cot 90°-3 cosec 90°

7 × 0 - 3 × 1

0 - 3

=3 ans. (because cosec is +ve in 1st quadrant)
