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. (e) There exists 0 < x < 1 such that e sin 1 = cosx (e - 1). Solution. • (a) True. (Follows from the mean value theorem.) • (b) False. (For example, /(x) ... Oct 14, 2023 ...

Now, we can see that both sides are equal: sin2x2​=sinxcosx2sinxcosx+cos2x−sin2x​ Thus, we have proved the identity. Mar 30, 2022 ... We evaluate the limit of 1-cosx / x^2 as x goes to 0. We'll find it equals 1/2 by using a conjugate and two previously proven results. Let's prove the given trigonometric identity. Step 1: Rewrite the given expression. The given expression is: cosec(x) - cot(x) / 1 - cos(x). If y 6= 0 then we must have cosx = 0 which implies sin x ∈ {1, −1}, but for all y ∈ R we have e−y + ey > 1 and the second equation cannot hold. Thus the ...
