In which of the four quadrants is :

(a) sin θ > 0 (b) tan θ < 0 (c) cos θ < 0

(d) sin θ < 0 and Tan θ < 0 (e) sin θ > 0 and cos θ < 0

(f) cos θ < 0 and Tan θ > 0 (g) cos θ > 0 and tan θ > 0 ?

(a) sin θ > 0 in first and second  quadrant

(b)tan θ <  0   in second and fourth quadrant

(c)cos θ < 0  in second and third quadrant

(d)sin θ <  0  and  Tan θ < 0 in fourth quadrant

(e)sin θ > 0 and cos θ < 0 in second quadrant

(f)cos θ <  0  and Tan θ > 0 in third quadrant

(g)cos θ > 0  and tan θ > 0 in first quadrant

a. in 1st quadrant and 2nd quad, Sin is +ve. i.e. >0.

b. In 2nd 4rth quad. tan is -ve, i.e. <0.

c. In 2nd and 3rd cos -s -ve i.e. <0.

d.In 4rth quad, sin and tan are -ve.So
