Draw a right triangle ABC so that m∠C = 90°
The lengths are:
Side a is opposite ∠A,
Side b is opposite ∠B,
Side c (the hypotenuse) is opposite ∠C
Because cos A = x, therefore
x = b/c => b = cx (1)
Because sin A = y, therefore
y = a/c => a = cy (2)
By definition,
tan A = a/b
= (cy)/(cx)
= y/x
Answer: b. y/x
