 theta = 0:1:90;
 3010 == Xo + (V .* cosd(theta)) .* t

I'm trying to calculate the angle needed to travel 3010 ft but I keep getting this error message

Arrays have incompatible sizes for this operation.

Error in lab2 (line 30)

3010 == Xo + (V .* cosd(z)) .* t

What is size(t)

Aidan Palermo el 20 de Sept. de 2021

t = linspace(0, 5, 900);

Xo = 1234;

V = 20000;

syms theta

t = .1:.1:1;

eqn = 3010 == Xo + (V .* cosd(theta)) .* t

eqn =

thetas = double(arrayfun(@(E) vpasolve(E), eqn));

plot(t, thetas)
