Find the value of sin270.


Open in App
Solution

Find the value given trigonometric expression.

Given, sin270can be expressed as, sin270=sin(180+90)

Since sin is a periodic function of time period 2π, also negative in third quadrant or sin(π+θ)=sinθ,whereπ=180

Therefore,

sin270=sin(180+90)=-sin90=-1sin270=-1
Hence, the value of sin270is-1.
