Question

Please write a simple Matlab program for these functions. I have already done a few however I am kinda lost these last three.

So for converting degrees to radians is would be something like this I think

funciont D_to_F

degrees=input('Enter radians')

degrees*pi/180

Is this correct? Or how would you do it?

1.Convert degrees to radians

2.Calculate the area of a circle

3.Calculate the area of a triangle

4. Calculate the tan and cot of a value in radians (in one function)

Answers:

a)Function to convert Degrees to Radians:
Source Code

function r = d2r(d)
%A simple conversion function
%Degrees to Radians
%Syntax: {angle in radians}=d2r({angle in degrees})

r=d/180*pi;

b) Function to Calculate the area of a circle:

function areacircle

% interactive program to compute area of circle

r = input(
