1. Multiple functions on the same graph: a. Define t using a sequenced vector over the interval [0, 2] with a step size of 0.01. b. Define following mathematical functions: i. gi(t) = 3 cos(10t) ii. 92(t) = 5exp(-1.25t) iii. 93(t) = 5 cos(10t)exp(-1.25t) C. Create a new figure and plot the three functions on the same graph such that i. 91(t) has straight red color line. ii. gz(t) has dashed green color line. iii. 93(t) has dotted blue color line. iv. Add grid on. V. Add legend and label the first line with 'g1(t)', the second line with 'g2(t) and third line with 'g3(t)
