Sin Cos Tan Cosec Sec Cot

Sin Cos Tan Cosec Sec Cot. Given cosec A (sin B cos C + cos B sin C) = cosec A × sin(B+C) = cosec A × sin(180 – A) = cosec A × sin A = cosec A × 1/cosec A = 1 Question 6 If the angles of a triangle be in the ratio 1 4 5 then the ratio of the greatest side to the smallest side is (a) 4 (√5 – 1) (b) 5 4 (c) (√5 – 1) 4 (d) none of these Answer Answer (a) 4 (√5 – 1) Hint Given the.

Since the derivative of tan inverse x is 1/(1 + x 2) we will differentiate tan1 x with respect to another function that is cot1 x For this we will assume cot1 x to be equal to some variable say z and then find the derivative of tan inverse x wrt cot1 x Assume y = tan1 x ⇒ tan y = x Differentiating tan y = x wrt x we get sec 2 y (dy/dx) = 1.

Let us now look into the differentiation formulas for different types of functions Differentiation Formulas For Trigonometric Functions Sine (sin) cosine (cos) tangent (tan) secant (sec) cosecant (cosec) and cotangent (cot) are the six commonly used trigonometric functions each of which represents the ratio of two sides of a triangle.
