Hello guys, I am stuck for two days about an issue. I have to create a solution matrix for the following two trigonometric functions.

m*cos(a)+n*cos(b)=x

m*sin(a)+n*sin(b)=y

0<a<180 , 0<b<180

m,n,x,y are constants. a,b are unidentified.

How can I solve x,y as matrix solution?

I will trigger x,y values with FRAME, so at each X.i, Y.i values I have to calculate a,b degrees and draw lines.

I am using MathCAD 15.

I would really appreciate your help. Thanks in Advance!

Re: 2 Trigonometric function with two unidentified

You would like to create an animation if you use the FRAME variable?

Let us create one frame of this animation!

Re: 2 Trigonometric function with two unidentified

Thank you for your intention @ValeryOchkov

I'll show with sketch in add.

There is K.i matrix. It consists nodes that arm going to reach. Arms are should be rectangular boxes. I wrote the translational and rotational matrix. Arms are working perfrectly fine. But it needs target node in order to calculate teta1 and alpha angles.

For example K.1 is (x,y)=(450,600)

It will calculate these angles then will go to K.2=(460,590), later on K.3=(465,582) and so on.

I will later make K.i matrix with bezier if I can finish this earlier. It has manual nodes added by me now.

I hope I could explained myself clearly. Thank you!

Re: 2 Trigonometric function with two unidentified

When a function with sin and cos, it's easier to make matrix solution. However in my function, there are only cos or sin one function . I have to make a general matrix solution. I am sorry I couldn't understand by your point. What do you suggest me to do exactly. I need this kind of solution below:

Re: 2 Trigonometric function with two unidentified

Thank you really but I gave it as an example. The actual functions I ask are in The main post. I know this one...
