Evaluate the limits of the following function using the appropriate properties of Limits or the result of The Squeeze Theorem if it exits (i.e. do not use numerical or graphical method, including L'Hospital Rule). Show all your work. sin (3x) 052-4x lim 2. (10 points) Let f(x)= (a) Find the derivative of f at (1,1) using the differentiation rules. (b) Find the derivative of f at (1,1) using the limit definition of derivatives.
