y = 4x

4a = 4a

Yes, the point (a, 4a) lies on the graph of y = 4x.

Correct?

Thread 'Trigonometry problem of interest'

The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
