Answer:
1. cos(2π + θ) = cosθ
2. tan(2π + θ) = tanθ, cot(2π + θ) = cotθ.
explanation:
cot(2π + θ) = cotθ. The Trigonometric ratios of angle 2π - θ: Thinking of θ as an acute angle, 2π -θ ends in the 4th Quadrant where only cosine is positive. 2π -θ means going 1 full turn from A to A and then returning to the M' that means as much as θ.
Answer:
All statements are true.
Step-by-step explanation:
In a square, we have
all sides equal
all angles equal to 90 degrees
diagonals always bisect each other and at right angles.
Only square is the quadrilateral which satisfies all the above properties.
A parallelogram has diagonals which do not cut at right angles.
A rhombus has all sides equal but not all angles. Neither diagonals are equal in a rhombus.
