Ứng dụng của 1 - cosx trong việc nghiên cứu về lý thuyết số và hàm zeta Riemann?

The derivative of 1/cos(x) is tan(x)sec(x). This can be found using the quotient rule, or through trigonometric identities, since 1/cos(x) = sec(x). Nov 7, 2013 ... The trick is to use Then your integral becomes From this we get Substituting in the latter integral , this is immediately integrated to. As x approaches 0 from the negative side, (1-cos(x))/x will always be negative. As x approaches 0 from the positive side, (1-cos(x))/x will always be positive. Jan 21, 2013 ... ... 1-(cosx)2. Denote u=cosx, du=-sin(x)dx. A3. Both m and n are even numbers. Strategy: Use (cosx)2=(cosx+1)/2, (sinx)2=(1-cosx)/2. Q: ∫ (sinx)2*( ... We have to find the derivative of . We will differentiate this expression with respect to x . Therefore, the given expression's derivative is − 1 1 − cos ⁡ x. Page 1. Lecture 15.
