having trouble with the above value

y1=x1tand(theta1)((x12g)/(2(vcosd(theta1))2))+y; Is trajectory 1 calculation correct? (Pretest) Variable y1 must be of size [200 1]. It is currently of size [1 200]. Check where the variable is assigned a value. Make sure you generated the x-values using the range for this trajectory with =30. Double check formulas for typos and order of operations
