P1.3.3 - Trigonometric functions and graphs question 1

[Maximum number: 2]
Figure 2

Figure 2

Figure 2 shows a plot of part of the curve C1C_{1} with equation

y=5cos⁡xy=5 \cos x

with x being measured in degrees.
The point P, shown in Figure 2, is a minimum point on C1C_{1}

State the coordinates of P

The point Q lies on a different curve C2C_{2}
Given that point Q
- is a maximum point on the curve
- is the maximum point with the smallest x coordinate, x>0
