Witrynawe see that the expression is defined when sin(Ð) and cos(Ð) are not equal to zero. Thus, 9 n7r,n e Z where sin(9) = 0 and 9 — + n e Z where cos(Ð) = 0. Simplifying, we have , n e Z Notice that this covers the restrictions on 9 for cot(Ð), the simplified form of this expression. WitrynaAgain, before starting this problem, we note that the Taylor series expansion at x = 0 is equal to the Maclaurin series expansion. Step 1: Find Coefficients. ... The functions cos(u) and sin(u) can be expanded in with a Maclaurin series, and cos(c) and sin(c) are constants. We will see the Maclaurin expansion for cosine on the next page. google play movies my stuff
