Intersecting problems

Leon Nikolai Engelsvold shared this problem 4 years ago

Not a Problem

K(x)=If(0≤x≤20,30000 (1.04^(x)))

This is what im trying to do, im trying to find when K is the dubble of 30000. and i chose to do it the hard way, because i want to. and it dose not work

Intersect(K, y=(2*y(Intersect(K,x=0)))

this dont even work

Intersect(K,y=30000*2)

Intersect(K,y=60000)

why?

i dont see why it should not work?

i see this as a bug...

The same problem

Intersect(K,y=60000)

Try using the intersect tool on those two objects. Alternatively:

g(x)=60000
Intersect(K, g, 15, 20)

i KNOW the intersect tool

g(x)=60000
Intersect(K, g, 15, 20)

work. but the problem was that

Intersect(K,y=60000)

do not work for me. i would like to be able to do it all in one command. it should be posible, right?
