You can put this solution on YOUR website! equation for tangent function with a period of 3 pi/8 and phase shift of -pi/5
**
Equation for tan function: y=tan(Bx-C), Period=π/B, phase shift=C/B
For given problem:
period=3π/8=π/B
B=8/3
..
phase shift=-π/5=C/B=C/(8/3)=3C/8
-π/5=3C/8
C=-8π/15
..
Equation for given tan function: y=tan(8x/3+8π/15)
