When converting cotangent+5 into cos/sin do you do what I did and bring the 5 with them or do you do cos/sin +5?

Answer (3)

(cosx/sinx) + 5 =(cosx + 5sinx)/sinx;

When converting cotangent + 5 into โ…”/sin, you separate the cotangent term and the constant. The cotangent function is equivalent to the quotient of cosine over sine (โ…”/sinฮธ), so when you add 5 to cotangent, it becomes (โ…”/sinฮธ) + 5. You do not bring the 5 along with the โ…” and sin within the same fraction. Instead, you keep the constant term separate from the trigonometric function.
An example of a trigonometric identity involving cosine and sine is: sinยฒ ฮธ + cosยฒ ฮธ = 1, which demonstrates the fundamental Pythagorean relationship between sine and cosine, often used when dealing with trigonometric expressions.

When converting cot ( x ) + 5 to cosine and sine, write it as s i n ( x ) c o s ( x ) โ€‹ + 5 . The constant +5 should be treated separately from the cotangent function. This keeps your mathematical expression clear and accurate.
