Plz do not copy from chegg and bartleby there is wrong answer ..and do all the parts

a. Determine that; i. 2+mi/ 4 = ( 1 + 1 ) ii. ely+2ni+x = ez (CO1:P01 - 4 marks) b. Determine real (e'/z) in terms of x and y. (CO1:P01 - 3 marks) c. Use Euler's formula to prove that expression; elz = cosz + i(sin z) (CO2:P02 - 4 marks) d. Show that sin z is exists or not? (CO2:P02 - 3 marks) e. Verify that the derivatives of sinh z. (CO2:P02 - 2 marks) f. Solve the value of sinh(2 - iv9 ) as well as their modulus. (CO2:P02 - 4 marks)
