transformed trig

Ok so I’m going to do this really simple. As you may know, the frequency, l.o.o. and the amplitude all correspond to a parameter. The frequency corresponds to parameter b, the l.o.o. to k and the amplitude to a. But you have to remember that those can’t be negative. Of course a, b and k may be negative in the equations, but once you want the frequency, l.o.o. or the amplitude, it can’t be negative. That was pretty much all I wanted to say… sorry if it was short and cheap!:P

Magic trickkkk

Hey, I felt like showing you guys a little and easy math magic trick. First, choose a number from 1-10. Then double it, add 6 and divide by 2. You will then have to subtract that number frm the one you had at the begining. Now the number you have it your head is 3.

This trick is really easy, here’s why: You start off with a number, for example 5. You then have to double it, which equals to 10. You then add 6, =16, and then divide by 2, =8. Since we started with 5, doubled it, added 6 and then divide it by 2 again, it’s obvious that you will end up with 5 again, but with half of the number you added, which is 6. So, if you subtract that number from your original number, the rests will be the half of the 6.

You can choose to add whatever number you want, the answer at the end will always equal half the numer you added.

Number: 7

Double: 14

Add: 100

=114

Divide by 2: 57

Subtract 7: 50, which is the half of 100!
