solve tan^2 x =1 where x is more than or equal to 0 but x is less than or equal to pi

solev tan^2 x =1 where x is more than or equal to 0 but x is less than or equal to pi

The potential barrier is defined by V(x) = ((A^2-(x^2)*(b^2))^0.5 where x is less than or equal to A/b. First we want to sketch V(x) Then we run a particle into it wth mass m and energy E (which is less than A). Now that we have run the particle into it we are asked to derive an expression for the probability of penetration in terms of D = E/A and sin (y) = bx/A. Finally, we are to evaluate our expression...

A. Let f(x) be: x+(12/(1-x)) if x is less than or equal to -3 x+3 if...

A. Let f(x) be: x+(12/(1-x)) if x is less than or equal to -3 x+3 if -3 < x and x is less than or equal to zero ln(x) if 0< x is less than equal to 5 (x-5)/5+ln5 if x>5 answer and explain these answers B. Is f differentialble at x=5? justify your answer by evaluating the one sided limits of lim as x approches 5 (f(x)-f(5))/x-5

Let f(x)= kx^k-x^(k-1)-x^(k-2)-...-x-1, where k is an integer greater than or equal to 1. Prove the roots of f have absolute value less than or equal to 1. This is possibly using Cauchy's Estimates for Roots of Polynomials or Ostrowski's Theorem, but I'm not sure how to use them.
