Solving exponential equations (1 Viewer)

[Nws m8]

e^2x= 1
take ln on both sides
2x = ln 1
x = 0


e^2x= -2
take ln on both sides
2x = ln (-2)
No solutions

Sorry I made that question up, that's why solutions are weird lol but it's good practise I guess

Btw when you pull the power out, is it 2x = .... or x^2 = ....?

huh?

Oh so it is 2x, thanks

There is one thing which I absolutely cannot do no matter how much I practice: proving trig identities. That will be the reason I fail HSC maths.

1) should know all your identities
2) do as much practise as you can

Good luck with HSC

I do know all of them, but I always take myself in the wrong direction when applying them. The easier - medium ones I can do, but HSC level ones I can't.

Aaaand yeah, kinda wish I didn't do Industrial Technology or English Standard since they scale poorly, and also since I want to do engineering I should've done MX1 and MX2.

Its alright, first year math isn't very hard (I did 4u, and no its not just me who says that-even 2unit ppl say its not very hard)

For now, just concentrate on your HSC, don't stress about uni

Let me know if you need any help with anything

Night

When I done first year math several years ago I struggled with it. Perhaps they have dumbed it down since.

Nope
