Answers
Answer:
Here I have 5 equations:
eq1= DE*cos(alpha)-AC*cos(beta)-CE*cos(sigma)==-AD;
eq2 = DE*sin(alpha)-AC*sin(beta)-CE*sin(sigma)==0;
eq3 = CE*cos(alpha)+CB*cos(beta)-FG*cos(theta)-GE*sin(lambda)-BF*cos(delta)==0;
eq4= CE*sin(alpha)-CB*cos(beta)-FG*sin(theta)+GE*cos(lambda)-BF*sin(delta)==0;
eq5 = sigma - lambda == 1.815;
I've already specified other parameters as follows:
DE = 35.39;
AC = [35.51;40.51];
BF = [20.82;24.52];
CE = 4.31;
GE = 15.29;
FG = 3.5;
AD = 4.75;
CB = 6.5;
Where AC and BF are lengths that are variable with upper and lower bounds.
The only known angle will be beta which is also an input angle with range from 0 deg to 80 deg. I've tried using fsolve but this function can only deal with inputs that are constant not 'range'. Are there any methods to obtain the rest of five unknown angles as results of also a range of angle on the plot?
