cot is a short way to write 'cotangent'. This is the reciprocal of the trigonometric function 'tangent' or tan(x). Therefore, cot(x) can be simplified to 1/tan(x).

We're trying to prove that csc(-x)/sec(-x)=-cotx. You'll need to use reciprocal identities: secx=1/cosx cscx=1/sinx and also angle difference formulae: sin(x-y)=sinxcosy-cosxsiny cos(x-y)=cosxcosy+sinxsiny Here's the actual problem.

Mar 17, 2018 · The period of the ratio functions are pi The period of y=cot(x-pi/2) is the same because our function is not being modified by anything other than a shift to the right pi/2. In trig, we have the form f(x)=a*trig*(bx+c)+d. The different coeffecients and their meaning are listed below. a = Amplitude. In terms of sin/cos, this is what affects the cusps of the graph. for …

May 29, 2018 · For this question, we can use the Sum-to-Product and Product-to-Sum identities.. I'm lazy, so here's a picture of the identities.

Apr 16, 2015 · #color(blue)(cot x = 1/tan x# We are given the value of #tan x = .88#. #cot x = 1/0.88# #cot x = 100/88# #color(green)(cot x = 25/22#

Aug 29, 2015 · y^' = sec^2x - 1/(1 + x^2) I'll assume that you don't know what the derivative of "arccot"(x) is, so that we can use implicit differentiation to find (dy)/dx. First, start by rewriting your function as y = "arccot"(x) + 1/cotx" ", which is equivalent to y = "arccot"(x) + tan(x) Rerrange to get arccos(x) alone on the right-hand side of the equation y - tan(x) = "arccot"(x) This is …
