A mathematical proof is a sequence of statements that follow on logically from each other that shows that something is always true. Created Date: 9/11/2018 2:03:50 PMSummarizing Trigonometric Identities. The Pythagorean Identities are based on the properties of a right triangle. cos 2 θ + sin 2 θ = 1. 1 + cot 2 θ = csc 2 θ. 1 + tan 2 θ = sec 2 θ. The even-odd identities relate the value of a trigonometric function at a given angle to the value of the function at the opposite angle. Using this as a guide, we define the conditional statement P → Q to be false only when P is true and Q is false, that is, only when the hypothesis is true and the conclusion is false. In all other cases, P → Q is true. This is summarized in Table 1.1, which is called a truth table for the conditional statement P → Q.Answer. Exercise 3.2.9. Determine all values of x¯ such that the limit limx→x¯(1 + x − [x]) exists. Answer. Exercise 3.2.10. Let a, b ∈ R and suppose f: (a, b) → R is increasing. Prove the following. If f is bounded above, then limx→b− f(x) exists and is a real number. If f is not bounded above, then limx→b− f(x) = ∞.Maths revision video and notes on the topic of algebraic proof.Definition. A vector is an object which has both magnitudes and direction. It is usually represented by an arrow which shows the direction (→) and its length shows the magnitude.
