Example 1: Calculate f/(x) where f(x) = 1. 2x2 + 3 3. /x. - x-. 3. 2 f/(x) ... Similarly, (cot x)/ = -csc2 x, (sec x)/ = sec xtanx, (csc x)/ = -cscxcot x. Explain why the equation tanx + cotx = 1 does not have real solutions. First of all, we need to express tangent and cotangent in terms of sine and cosine using ... (x) = 24 csc. 4 x cot x − 8 csc. 2 x cot x. Observe that 1.5 < 7/2 ≈ 1.5708, that csc x ≥ 1 and cot x ≥ 0, and that both functions are decreasing on that ... ... x−Sm+1(x)x2(m+1)tanx=tanx−Sm(x)−22(m+1)(22(m+1)−1)Bm+1[2(m+1)]!x2m+1x2(m+1)tanx=1x2·tanx−Sm(x)x2mtanx−22(m+1)(22(m+1)−1)Bm+1[2(m+ 1)]!·cotxx=1x2m∑j=122(m−j+1) ... by comparing to L4(big(x),big(y)), i.e. arbitrary-precision calculation.)
