Animal cells have a cell membrane, which surrounds the outside of the cell to maintain its shape and to keep the cell components inside. They also have a nucleus, which contains all of the genetic mater...

we start  y factoring and solving for each equation:

cos(x) (2cos(x) - 1) = 0 

this means: 

cos(x) = 0 and cos(x) = 1/2

from the first equation we get:   x = 90

and from...

= 14x+21y-14x+xy

=y(21+x)

#Of course this question could be expanded into a program as large or small as desired, dependant on how rigorous wants the program to become. The setup I created here checks for some basic syntactical er...

Some of these examiners quite like asking students to find the derivative of an inverse trig or hyperbolic function to try and catch someone off guard. The best way to approach these is to first multiply ...
