Q: Find  sin?,cos?,???tan?sin⁡θ,cos⁡θ,andtan⁡θ  if  csc?=−2921csc⁡θ=−2921    and  cos θ < 0.

A: Given Cosecθ=2921and we have to calculate the value of sin(θ), cos(θ), tan(θ)

Q: Assume that Sin θ= 4/5 where π/2<θ<π  find tanθ

A:

Q: 2. Cos sin

A:

Q: (c) cos 27 (d) tan

A: Cos(π/4)= 1/√2= 0.707106781

Q: Find the exact value of tan [ 2 sin-1 (-12/13) ]

A: Given,  tan 2 sin-1-1213  We have to find the exact value of the above expression

Q: Give the exact value of sin (cos ()). 3

A: The objective is to find the exact value of the trigonometric function.

Q: Tan ( 3θ - 4 degrees ) = 1/ cot ( 5θ - 8 degrees)

A: Solve:

Q: If sin x and T <x < , find tan x exactly. !! 1/4

A: We can use trigonometric identities to find the exact value of trigonometric function. We can use…

Q: Find the tan x/2 = (1-cosx)/sinx under the conditions where tanx=-1/3 and cosx &gt;0. Draw a right…

A:

Q: Verify that it is an identity  (1-sec/tan)+(tan/1-sec)=-2csc

A: We will simplify left side and make it equal to right side

Q: simplify tan(a), if cos(a)= 4/7

A:

Q: Suppose -π/2 <θ < 0 and tan θ= -2 Evaluate (exactly) (a) cosθ (b) sinθ

A:

Q: (ii) Hence, without using a calculator, find the value of tan(22.5°

A:
