Question

Can you find sine cosine and tangent of a given angle? A given point? Find it on and off the unit circle?

Answer 1

The values of the trigonometric functions are: sin(x) = 2/√5, cos(x) = 1/√5 and tan(x) = 2

How to determine the trigonometric functions?

The trigonometric functions are calculated using:

• sin(x) = opposite/hypotenuse
• cos(x) = adjacent/hypotenuse
• tan(x) = opposite/adjacent

From the complete question, we have:

opposite = 2

adjacent = 1

hypotenuse = √5

So, we have:

sin(x) = 2/√5

cos(x) = 1/√5

tan(x) = 2/1 = 2

Hence, the values of the trigonometric functions are:

sin(x) = 2/√5, cos(x) = 1/√5 and tan(x) = 2
