How far have you got?

At the point where two curves intersect, what can you say about the value of each curve at that point?

Whenthey intersect they go through the same point ie the x and y coords are the same.

Try putting the two equations for y equal to each other.

Can you solve the equation you've got?

Could you send a pic of the question?

Its Q7 on the attachment
11. If you had could you solve it? (Standard angle)
12. Simultaneous equations, Tan(x+pi/5) = sqrt(3) (so that the equation is equal to the line)
Solve for x + pi/5 then solve for x.
13. Tan (x+pi/5) = root 3

Tan^-1 (root 3) = x + pi/5
Y = root 3

Ok I'll answer it for you: Where two curves intersect, they have the same value.

This means curve one equals curve two. (hint hint)

find one point of intersection of the curve y=tan(x+pi/5) and the line y= square root 3

This is my answer (2/15pi, root3)
