Verify the pythagorean identity 1 + c o t ^2 θ = c s c ^2 θ
Grace [21]

Answer: The identity is verified. See the explanation.

Step-by-step explanation:

You must keep on mind the following identities:

csc\theta=\frac{cos\theta}{sin\theta}\\\\csc\theta=\frac{1}{sin\theta}\\\\sin^2\theta+cos^2\theta=1

Therefore, by substitution, you can rewrite the identity as shown below:

1+cot^2\theta=csc^2\theta\\\\1+\frac{cos^2\theta}{sin^2\theta}=csc^2\theta

Simpliying, you obtain:

\frac{sin^2\theta+cos^2\theta}{sin^2\theta}=csc^2\theta\\\\\frac{1}{sin^2\theta}=csc^2\theta\\\\csc^2\theta=csc^2\theta

The identity is verified.

A moving company charges $40 plus point $.25 per mile to rent a van. Another company charges $25 plus point $.35 per mile to ren
nikdorinn [45]

Answer: 150 miles

Step-by-step explanation:

m = mile

40 + 0.25m = 25 + 0.35m

0.25 * 150 = 37.5

37.5 + 40 = 77.5

0.35 * 150 = 52.5

52.5 + 25 = 77.5

77.5 = 77.5
