Please answer all questions. Need to use MATLAB software and EXCEL to answer these questions.

(The following equations show a nonlinear system with t is time (s) while C is concentration (mol/m3) 2sint=t2/10t+C2=11 a) Using Graphical Method, plot both equations in a graph (USING MATLAB). b) Using the generated graph from Question 1(a), estimate solutions for the values of C and t. c) Using Iterative Method - Newton Raphson with Microsoft Excel, solve the system for the values of C and t d) Verify the solutions in Question 1(c)
