## Transcribed Text

Task 1 (17 pts): In an *.m file, load in the same SampleECG data provided in Lab 1. Create a new array containing the second half of the SampleECG signal (samples 129:256). Invert the signal by multiplying each element of the signal by -1. What is the minimum value of this signal? What is the maximum value of this signal? What is the vector length of this signal? Task 2 (17 pts): Create a new array that contains all numbers from 1 to 24 using " operator. Calculate a new array by finding the square root of each number in your array. Find the total sum of all numbers in this array. What is the natural logarithm of that value? Hint: ansuer 4.3899 Task 3 (16 pts): Prompt the user to input any two separate variables into MATLAB. Assign variable IT to be the ratio of the two variables. Calculate the following function of this ratio tan(r7) y = + Vr++1 sin(rr - 1) + cos(rr + 1)
