Answer:
this is geometry?
Step-by-step explanation:
4th quadrant is positive x (cos) and negative y (sin)
Use the Pythagorean Theorem to calculate the value of y (sin).
x² + y² = c²
5² + y² = 13²
25 + y² = 169
y² = 144
y = 12
Since the y-value is negative in the 4th quadrant, then y = -12
Answer:
- cos (x) cos (2x) - 2sin(x) sin(2x)
