Casio "ClassPad 300" is my choice. -
Not taking credit away from anybody, my intention was to inform about the nice page by NASA for those who have not seen it before.

It is an incorrect theory as per NASA. Pls check the following link. http://www.grc.nasa.gov/WWW/K-12/airplane/wrong1.html

Hint: Consider the equilateral triangle with base=10v, and height=3400. So, half base=5v. Check that tan(15)=5v/3400, v is in mt/sec, angle in degrees.

Very nice and quite emphatic.

Substitute, x= 1/z. Then, apart form the constants, the integral becomes of the form 1/sqrt(4/9-z^2). The final answer should be (1/3).arcCos{3/(2x)} +C [or, -(1/3).arcSin{3/(2x)} +C].
