Why are these two equal? \tan^2(t) + \sin^2(t) = \sec^2(t) - \cos^2(t) Why is -2^2 equal to -4? What does 8 times 9 equal? For what values of a and b is g(x) = ax + 2b, if x is less than or equal to 0; x^2 + 3a - b, if x is between 0 and 2;...
What does ex equal? Graphing exponentials: The nature of exponentials is quite interesting. The ′e′ in ex represents an important mathematical constant. The number e attains a value of around 2.718. Answer and Explanation: ex can be graphed by plotting some points in the cartesian plane ...
Tan = o/a Tangent of an angle = opposite over adjacent. Here are the other Trig. functions. SINe(angle) = opposite/hypotenuse COSine(angle) = adjacent/hypotenuse COTangent(angle) = adjacent/opposite Cosecant(CSC)(angle) = hypotenuse/oppositre SECant(angle) = hypotenuse/ adjcent....
Can cos ever exceed 1 or drop below -1? No, cos values are strictly between -1 and 1. 8 How does the Taylor series expansion compare between cos and cosh? Both cos and cosh can be expanded into a Taylor series, but while cos alternates between even powers of x with factorial denomina...

How do you prove the following identity sec x - cos x equals sin x tan x? you need this identities to solve the problem..that is something you have to memorized sec x= 1/cosx 1-cos2x= sin2x tanx= sin x/cosx also, sin 2x= (sinx)(sinx) sec x - cosx= sin x tanx (1/cosx)...
Does it really mean "90-degrees"? How do we construct the observer's x-axis (her "spaceline") given her t-axis (her "timeline"), starting from a "circle" (which is what defines orthogonality)? Is relativity really "so unlike anything we have ever seen" or can it be...
What Does θ Mean in Trigonometry? θ in trigonometry is used as a variable to represent a measured angle. It is the angle between the horizontal plane and the line of sight from an observer's eye to an object above. θ can be referred to as the angle of elevation or angle of depress...
