I find it is best whenever you open your maths paper to draw this diagram to help you remember: Sin(X) -> cos(X)-> -sin(X) -> -cos(X)----->{Drawn in a circle on the board} To diff...
Assume y = 2x + pi/2, Since the period of 'tangent' is pi, the general solution of 'y' to valid the equation of tan(y) = SQRT(3) is the form of y = npi+pi/3 where 'n' is any positive or negative...
a) In one week he will drive drive twice, each day the probability of getting caught is 1/100 and not getting caught is 99/100. using a probability tree diagram, we can see there is only one possible outc...
Before we blindly start using the integration by parts formula, we can see that no matter how many times we differentiate or integrate sin(x) we will still have a trigonometric function. The aim of the 'b...
When integrating, we raise the power by 1 and divide by the new powerSo, 2x5 becomes 2x6 /6 which simplified down as the question asks is x^6/3-1/(4x3) is -(1/4)x^-3<...
