Question

Write the valuevof cot 2theta -1/sin2theta or if sin theta -cos theta ,fins the value of 2tan theta +cos 2theta

Answer 1

Answer:

Sin theta = cos theta (given

Step-by-step explanation:

sin theta / cos theta = 1

tan theta = 1

theta = 45°

now,

2 tan theta + cos^2 theta

putting theta = 45°

2 tan 45° + cos^45°

2*1 + ( 1/√2 )^2

2 + 1/2 = 2*2+1/2 = 4+1/2 = 5/2

Answer : 5/2
