Question

if sin theta +cos theta= root 2 cos theta determine cot theta​

Answer 1

Answer:

1/(√2-1)

Step-by-step explanation:

sinX+cosX=√2cosX

SinX=√2cosX-cosX

SinX=(√2-1)cosX

sinX/cosX=√2-1

TanX=√2-1

CotX=1(√2-1)

Answer 2

Answer:

cot theta=√2+1

Step-by-step explanation:

sin theta + cos theta = √2 cos theta

tan theta + 1 = √2

tan theta =√2-1

cot theta = 1/√2-1

Now rationalize

ans cot theta = √2+1
