Question

If sin theta + cos theta = root 2 sin (90 - theta) show that cot Theta = root 2 +1​

Answer 1

Answer:

Let theata be A

sinA + cosA root 2 cos (90-A)

SinA +cosA= root 2 sinA

CosA = root 2sinA - sinA

CosA = sinA (root - 1)

CosA/sinA =(root - 2)

So, cotA= root 2 -1

hope it helps u....

Answer 2

Answer:

Step-by-step explanation:

Let theata be A

sinA + cosA root 2 cos (90-A)

SinA +cosA= root 2 sinA

CosA = root 2sinA - sinA

CosA = sinA (root - 1)

CosA/sinA =(root - 2)

So, cotA= root 2 -1
