Are there any other values of a such that the linearization of sin(x) at a = the linearization of tan(x) at a? Describe them through proof if they exist. If they don't exist, proove that instead.

    FIrst, write down the linearization for both functions, using \[ f_{a1}(x) \approx f_1(a)+ f_1'(a)(x-a) \\ f_{a2}(x) \approx f_2(a)+ f_2'(a)(x-a)\] then equate terms \[ f_1(a) = f_2(a) \\ f_1'(a) = f_2'(a) \] and solve for a
