Matlab help please!

    I'm trying to solve the following problem using a matlab script but I keep getting an error:

    Show on the same axes the maximum height and horizontal distance travelled for an object thrown at a speed of 10ms-1 at an angle ranging from 0 to π/2. Equation for distance & height are:

    D= v2/g sin(2θ)

    h= (v2/2g) sin2θ


    This is my code:

    Code (Text):
    g=9.81; v=10;
    legend('horizontal distance','maximum height')
    When I run this code the graph doesn't come up and I get the following error:

    Any help here is very much appreciated. :smile:

    There is an "end" but nothing is started e.g. "if, while" etc. Also you did not define variable "y"

    Code (Text):

    g=9.81; v=10;
    legend('horizontal distance','maximum height')
    This should work...
