Find the Sine Given the Point (-4,3)
Problem
Solution
Identify the coordinates of the given point as
x=−4 andy=3 Calculate the radius
r using the distance formular=√(,x2+y2) Substitute the values into the formula:
r=√(,(−4)2+3)=√(,16+9)=√(,25)=5 Apply the formula for the sine of an angle in standard position, which is
sin(θ)=y/r Substitute the known values
y=3 andr=5 into the ratio.
