Suppose that is an angle such that sin() = 12 13 and cos(): = 5 13 Is 0= arcsin 12 13 ? Why or why not?

Q: if sine + cose = 2 sin( 90° – 0),determine cote

A: use the property of trigonometric function to find the desired value.

Q: The angle 0, is located in Quadrant III, and tan (61) = 15 cos (6,) = cot (61) = csc (61) = sec (6,)…

A:

Q: Write sin A as

A: This question is about trigonometric identites

Q: Find the remaining trigonometric functions of theta if sin theta = 1/2 and terminates it

A: Given: sinθ=12 we know that sinθ is positive in first and second quadrant if, θ is in first quadrant…

Q: Suppose cos ? =15/17 and ? lies in the 4th quadrant. Choose one of those ways to find sin ?.

A: Solution is in step 2

Q: When a and b are real, we define elatiblx with the equation ela+ ibix = eax , eibx e"(cos bx + i sin…

A: we know that am+n=am.an similarly, ea+ibx=eax+ibx=eax.eibx now, we know that eiθ=cosθ+isinθ

Q: Find cos\theta if cot\theta =(2)/(3) and \theta is in Quadrant III.

A:
