The function arccot is defined as the inverse of the cotangent function restricted to the interval (0,π). Suppose we define a function f by f(x)=cot(x) for x in the interval (2⋅π,3⋅π) and let g be the inverse function to f. find g(-1)
Hint: Substitute x with -1 for g(x) and evaluate. Do the same for g(√3).
Suppose we define a function f by f(x)=cot(x) for x in the interval (2*π,3*π) and let g be the inverse function to f. Give the domain of g. Find the values of g(sqrt(3))= and g(-1)=
i found g(sqrt(3)) to be 13/6 pi but i cant find g(-1)
Substitute it
what is g(x) look like
\[f(x)=cot x\] \[g(x)= 2\pi+ \cot^{-1} x\] \[g(-1)=2pi+ \cot^{-1} (-1)\] arccot -1= 3pi/4 so \[g(-1)= 2\pi+3\pi/4\]
thanks so much
y = f(x) = 1/tan(x) --> tan(x) = 1/y --> x = g(y) = arctan(1/y) g(-1) = arctan(-1) = 3pi/4 in interval 2pi to 3pi, add 2pi 2pi + 3pi/4 = 11pi/4
ok i got it
