Use the sum of angles's trigonometric identity formula:
cos(A+B)=(cosAcosB-sinAsinB)
x+y=4cos(t+π/6)+2sint=4(cost*cosπ/6-sint*sinπ/6)+2sint
recall that cosπ//6=√3/2, and sinπ/6=1/2:
4(cost*cosπ/6-sint*sinπ/6)+2sint=4[(√3/2)cost-(1/2)sint]+2sint
simplify:2√3cost-2sint+2sint=2√3cost

The image of (2, - 1) after a translation of (x, y) + (x -1, y+3) is
Arturiano [62]
The rule for the translation is like a function. If X=2 and Y=-1, we just substitute those values in the rule of (x,y) => (x-1, y+3)

(2,-1)=>(1, 2) are the new coordinates. You went 1 to the left on the X axis and 3 up on the Y axis.
