physics - energy question
A simple pendulum, 2.0 m in length, is released with a push when the support string is at an angle of 25° from the vertical. If the initial speed of the suspended mass is 1.2 m/s when at the release point, what is its speed at the bottom of the swing? (g = 9.8 m/s2). i ...

Music
I was wondering about transposing. Suppose I had to transpose something that's written for piano (F major with one flat) to let's say Bb clarinet (G major with one sharp). My question is what method can I use to determine how many flats or sharps the second instrument ...

Find the intervals on which y=1/(x^2+1)^2 is increasing and decreasing. find the first derivative which is -4x/(x^2+1)^3 you should know that if the first derivative is positive, then the function is increasing and if it is negative, the function is decreasing. Now by ...

Calculus
Find the equation of the tangent line to the graph of f(x)= (8x^2-3)/(x^2+4) at the point where x=-1. Take the derivative of f(x). That gives you m, the slope. Then, y= mx + b Put in x,f(x) for x,y. Calculate b. I get it now. Thanks for your help!
