Assignment:
In terms of radians and X, what would be the specifications of the anlges for trigonometric points which result from the following transformations of the trigonometric point P(X)? (Work these out on a diagram of the unit circle)
1) A reflection y = x followed by a rotation through pi
2) A reflection in y = -x
3) A reflection in the x axis followed by a rotation in the y axis
4) A rotation through -pi / 2 followed by a reflection in the y axis.
In each case, give the corresponding related angle formulas involving cos & sin.
Provide complete and step by step solution for the question and show calculations and use formulas.
