The value of |a| is called the amplitude and c is the phase angle ... setBorder(0); initPicture(-5,5.01) axes(1, 1, "labels", "grid") stroke ... Jan 23, 2019 ... Answer: 1 Step-by-step explanation: 1. Convert the denominator to cos terms. 2. Further add the terms in the denominator. 3. Take SinxCosx ( or Sin theta cos ... Let's prove the given trigonometric identity. Step 1: Rewrite the given expression. The given expression is: cosec(x) - cot(x) / 1 - cos(x). ... 1(x)cot(x)+(2k−1)∫csc2k−1(x)dx]. Proof: ∫csc2k+1(x)dx=∫csc2k−1(x)csc2(x)dx. Using integration by parts: Let u=csc2k−1(x). then du=−(2k−1)csc2k−1(x)cot(x)dx. Oct 16, 2014 ... .I csc2 x dx =- cotx+C.
