• ### Why when we do things for others, we do well, but when we do something for ourselves, we just can't?

Well, have you had this type of experience? In which when you want to help somebody out, you try your best and do it well, but when it comes to doing it for your own good, we sometimes fail, or just have it at an average level?

Guys, what are the answers to these questions?

1. Integral of secant theta from 0 to pi.

2. 3^x+4^x=6^x, Find x.

Thanks.

• ### A function that converges nor diverges?

It involves Newton's method of finding roots.

Find a function, f(x), which has a single root, x*, for which newton's method neither coverges nor diverges. For any initial guess the iterations of Newton's method oscillate equidistant about x*.

I'm making this into a MATLAB code.

• ### Can someone answer this thermodynamics question?

The mass of a given airplane at sea level is (g= 32.1 fps^2) is 10 tons. Find its mass in pounds when it is travelling at 50,000 feet. the acceleration of gravity g decreases by 3.33x10^-6 fps^2 for each foot of elevation.

The answer given is 20000 lbs.

I couldn't get that, i was just thinking of a simple conversion from Kg to pounds which was 22000 pounds.

• ### How to build a simple IR switch?

I'm planning to make a simple IR switch.

Usage:

A switch is triggered, the IR reciever detects the IR signal and switches ON a LED.

or

When the switch is triggered, a switch closes and switches on a device.

Just a simple switch, just one signal. I've tried looking into remote controls, but its too complicated with binary and such.

Please include circuit diagrams if you have any. Thanks!

• ### Use of guitar scales?

I learned the guitar scales, the major and minor, i'm currently practicing the fingering technique to memorize the positioning of the notes. I wanna improve my lead guitar ability.

Now, i've asked a few guitarists, and they say thhat if youlearn the scales, you can play lead immediately. This has left me blunt and just staring at the fret board! :))

I've practiced the major key of G, how do i use it? if i want to play a key of A or B do i just move the finger positioning 2 frets or 4 frets?

And another thing, for example, if the song's chords are E, C#m, A, when applying lead, do i use the E major scale, the C#m scale and A major scale?

Any help would be appreciated. Thanks!
