What is the primary module in the Smart Phone as a Key (SPaaK) system?
Answer (3)
(cosx/sinx) + 5 =(cosx + 5sinx)/sinx;
When converting cotangent + 5 into ⅔/sin, you separate the cotangent term and the constant. The cotangent function is equivalent to the quotient of cosine over sine (⅔/sinθ), so when you add 5 to cotangent, it becomes (⅔/sinθ) + 5. You do not bring the 5 along with the ⅔ 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: sin² θ + cos² θ = 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 ) + 5 . The constant +5 should be treated separately from the cotangent function. This keeps your mathematical expression clear and accurate.
