1 If cos(0) and 0 is in the 1st quadrant, find the exact 7 value for sin(0). sin(0) = %3D

Q: Find cos 0 if cot 0 =4/3 and sin 0 < 0.

A: Also given that sinθ<0, this means sinθ is negative. So, cotθ=cosθ/sinθ means cosθ also have to…

Q: If sin(0) 4 and e is in quadrant III , then find (a) cos(0) (b) tan(0) (C) sec(0) (d) csc(0) : (e)…

A:

Q: Suppose sin(0) = -2/3 where 0 lies in Quadrant IV. Use this to find tan(20).

A:

Q: 4. Find the exact value (in exact form) of sin

A: cos(2x) = 1-2sin2(x)

Q: If cos(8) 1 and 0 is in the 3rd quadrant, find sin(0) %3D 6. sin(0) = %3D

A: Given: Since, So,

Q: 3 If sin(0) and 0 is in quadrant II, then find 7' %D

A:

Q: sin20 + sin e = 0

A:

Q: If sin 0 = 2π (77) 11 = Check Answer cos(0) and 0 < 0< then T 2 radians

A:

Q: Evaluate: " sin7 cos4 dx

A:

Q: If cos(0) 7. and 0 is in the 4th quadrant, find sin(0) 8. sin(A)

A: Since, cos θ=78and θ is in the fourth quadrant.Our Aim is to find sin θ=?

Q: f sin(theta)=4/5,0<theta<pi/2, find sin(2pi)

A: Here given  sin θ=45 where 0&lt;θ&lt;π2 Thus cos θ=1-sin2θ=1-452=1-1625=925=35

Q: Use the double-angle formula for cosine to compute cos(20) given cos( os(0) = where 0 <0<. 79 90

A: Given.

Q: sin(0) = os (0) = COS - 113 and the terminal side of is in quadrant IV.

A:

Q: If cos(0) and 0 is in the 4th quadrant, find the exact value for sin(0). 8. sin(0) - !!

A: sine is negative in fourth quadrant and cosine is positive .
