Prove that each of the following identities is true.     tan A/sec A = sin A

Q: Prove the identity. Work on one side only. cos(4x) = 1 – 8 sin² x + 8 sin²x

A:

Q: 1 Show that (tan-' x) : 1+x?

A: We use Trigonometry identities and inverse Trigonometry to solve this proof

Q: 8. Show that sin a (1+ tan a) + cos a (1 + cot a) = sec a + csc a.

A:

Q: 3. Verify each of the following identities. b. csc(20) = sec 0 csc 0 CSC

A:

Q: Sec A - cos A is identically equal to

A:

Q: Find the Tan θ given the Sin θ = -1/3 and Sec θ is positive

A: Given  Sin θ=-13 The objective is to calculate Tan θ. Use the following 1. sec θ=1cos θ2. tan θ=sin…
