If sinθ=−1√2 and tanθ=1, then θ lies in the
Given sinθ=−1√2 and tanθ=1
sinθ is negative and tanθ is positive.
sinθ is negative either in third or fourth quadrant.
It is also given tanθ is positive. In third quadrant tanθ is positive while in fourth quadrant tanθ is negative.
So, θ should lie in third quadrant.
