Answer:
<h3>-π/12</h3>
Step-by-step explanation:
Which radian measure is equivalent to −15°? −9π/20 −12/π −20π/9 −π/12
180 degrees = πrad
-15 degrees = x
Cross multiply
180x = -15π
x = -15π/180
x = -π/12
Hence the value of -15 degrees in radians is -π/12

Answer:
amplitude = 3
period = 
Step-by-step explanation:
Comparing the equation with the general equation :

Where :
A = amplitude
period = 
D = vertical shift
Therefore : with the comparison :
amplitude = /-3/ = 3
period =
