Hint: Use the identity sin2 x + cos2 x = 1. Sol. /. 1 sin2 xcos2 x dx ... (tanx − cotx + C) = sec2 x + csc2 x. • Find f by solving the initial value ... by comparing to L4(big(x),big(y)), i.e. arbitrary-precision calculation.) (b) Write a function cotdiff(x,y) that com- putes cot(x) − cot(x + y). Does your ... May 25, 2016 ... The answer is : tan x > (1 + tan x)/(1 + cot x) = (1 + tan x)/(1 + 1/(tan x) = (1 + tan x)/(tan x + 1)cdottan x =cancelcolor(red)(1 + tan ...

The following question is asked under a section on Trig Identities Simply states Simplify cosec x + cot x We managed to get this far: 1 sin ⁡ x + cos ⁡ sin ⁡ x. (1 - cosx). [cos(1. 2 x)]. 2. = 1. 2. (1 + cosx). Sums and differences of angles ... - x) = cot(x) tan(x + π) = tan(x) tan(x - π) = tan(x) tan(π - x) = -tan(x). ) 1+tan² x = sec² x. 9.) 1+ cot² x = csc² x sin² x. 2 so that so that tan² x = sec² x - 1 cot2x = csc² x - 1. 10.) Jo. 1 ... csc x dx. = ln csc x x- cot x + C. 1. cos (x) = 1 / sec (x). The cosine of ex equals one divided by the secant of ex. tan (x) = 1 / cot (x). The tangent of ex equals one divided by the cotangent of ...
