## mo7892 2 years ago can you prove that (m+n)cotθ=mcotθ-ncotθ

1. shubhamsrg

Can i ?

2. klimenkov

Obviously, this is not right.

3. AravindG

is that possible?

4. AravindG

it can nevr be true

5. hartnn

only if n=0

6. mo7892

i have a non right angle triangle ABC which the base is length m and n. and its divided into two by two angles beta and alpha

7. hartnn

do you have a figure ?

8. mo7892

let me draw it

9. mo7892

i have drawn it but how do i send it for you

10. mo7892

how do i send the figure

11. hartnn

you can draw the figure using 'Draw' button below, or you can attach the image file using 'Attach File' button...these buttons are on the left of Post button.

12. klimenkov

And don't forget to click the "Post" button.

13. mo7892

let me know if you can see the diagram

14. hartnn

no, can't see..

15. mo7892

they have said use the trigonometric theorem (M+N)COTθ=MCOTα-NCOTβ

16. mo7892

try no 2 second attachment.

17. mo7892

18. mo7892

can you let me know if you can see it
