(1) An impulse causes calcium ions to enter the axon. (2) Vesicles fuse with the presynaptic membrane. (3) This causes the release of acetylcholine. (4) Acetylcholine diffuses across the synaptic cleft. (...

Method:We use the trigonometric identity (tanx)^2 +1 = (secx)^2 to understand that (tanx)^2 can be written as (secx)^2-1.We then use the formula booklet to identify that (secx)^2 i...

A while loop is used in situations where we do not know how many times a loop needs to be executed beforehand.A for loop is used where we already know the number of times loopneeds to be executed.For exam...

e.g. given x^2 +3x -8 = 0using the quadratic formulayou find x = (-b +- sqrt(b^2 -4ac))/2ayou then find one root using the plus instead of plus minus sign, and the other root using the minus instead of pl...
