Programming solve function
I am having trouble programming the SOLVE and fsolve functions, and I am not sure of what I am doing wrong. I can run solve on the HP Prime, but I can't programmatically solve the equation.

EDIT 6/4/18 corrected error in code with the radius, but still can't get code to work.
Code:
EXPORT OldAAngleSetting,theta,radius,x,q,v; EXPORT SolveProgramExamples() BEGIN OldAAngleSetting:=AAngle; //save apps angle mode setting AAngle:=1; //Switch to apps radian angle mode // SOLVE Example ---------------------------------------- //initialize variables X:=0; theta:=0; //input V:=2; R:=0.75; Q:=3.1; Solve.SOLVE(X-SIN(X)=2*Q/(V*R^2),X,3); theta:=X; PRINT(); PRINT("SOLVE example"); PRINT("X="+X); PRINT("theta="+theta); // fsolve Example ------------------------------ //initialize variables x:=0; theta:=0; //input v:=2; radius:=0.75; q:=3.1; theta:=CAS("fsolve(x-SIN(x)=2*q/(v*radius^2),x=3)"); PRINT(" "); PRINT("fsolve example"); PRINT("x="+x); PRINT("theta="+theta); AAngle:=OldAAngleSetting; //restore previous apps angle mode setting END;
