Question

If tan x = -2 , find the value of sin x ( x lies in the II Quadrant). Ans With Steps

Answer 1

Answer:

tanx = -2

X lies in the 2nd Quadrant.

In the 2nd quadrant, sine and cosec are positive. Hence, we know that

tanx = -2/1

sinx =

$\frac{ - 2}{ \sqrt{ { - 2}^{2} + {1}^{2} } }$

=

$\frac{ - 2}{4 - 1}$

= -2/3.

However sine X is positive in the 2nd quadrant. Hence the answer is 2/3.
