Question

If sinθ + cosθ = √2cosθ, (θ ≠ 90o) then the value of tanθ is​

Answer 1

Answer:

tan2ø=1

tan45=1

i.e. 2ø= 45

ø=45/2=22.5

therefore, tanø=tan22.5=0.556

Answer 2

Step-by-step explanation:

SinQ+CosQ=√2cosQ

both side dividing by CosQ

SinQ/CosQ+CosQ/CosQ=√2CosQ/CosQ

TanQ+1= √2

TanQ= √2-1
