It is true for all the values of $\theta$ in the unit circle.Using this first Pythagorean Identity, we can find the rest of the Pythagorean Identities.$sin^2\; \theta + cos^2\; \theta = 1$Dividing each term by $cos^2 \theta$$\frac{sin^2\;\theta}{cos^2\;\theta} + \frac{...
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)...
The first angle goes, “Hey Thelma (or is it Theta?), I don’t mean to go off on a tangent here, but what’s your sine?” To which the second angle replies, “Phil (or is it Phi?), I don’t know why you even bother to ask, my sine is obviously the same as your cosine...

The length of the hypotenuse of a30∘−60∘−90∘triangle is 18. What is the perimeter of the triangle? The Trigonometric Ratios: The trigonometric ratios connect the three sides of a right-angled triangle and the acute angles. Some three ...
a Structural synaptic scaling is analyzed by serial section electron microscopy in hippocampal tissue under control and LTP (induced via theta burst stimulation) conditions. Control and LTP dendrites have equal postsynaptic areas (red outline) despite differences in synaptic density and size. Adapted ...
