# Ex no:2d Evaluate the expression

**AIM:**

To write a C program to evaluate

x = 8t^{2}-t+4

y=sin 30◦

z=e^{3t+5 }

**ALGORITHM:**

**Step 1: **Start the program.

**Step 2: **Read t.

**Step 3 : **Calculate

x = 8t^{2}-t^{3}+4

y=sin 30◦

z=e^{3t+5 }

**Step 4: **Print the value of x,y and z.

**Step 5:** Stop the program.

**PROGRAM CODE:**

#include<stdio.h> #include<conio.h> #include<math.h> void main() { float x,y,z,t; clrscr(); printf("Enter the value of t :"); scanf("%f",&t); x=8*pow(t,2)-t*t*t+4; y=sin(3.1415*30/180); z=exp(3.0*t +5.0); printf("nx = %.3f, y = %.3f, z= %.3f", x,y,z); getch(); }

**OUTPUT:**

**RESULT:**

Thus the C program to evaluate given expressions is written and executed successfully.
