sin^5 2x = 1/8 sin2x (cos(8x) - 4 cos(4x)+3)
That depends on your profession. If you are a math teacher, then you might use a lot of Trig. If you are an engineer, working with forces on any object from different directions, then you would use trig. Electrical engineers use trig. Surveyors use trig.

Trig ratios or to give them their proper name are trigonometrical rations applicable to right angle triangles and they are tangent ratio, sine ratio and cosine ratio.
Can you verify your identity.
Can you verify your identity.
To find an angle without using a calculator, you will need to use a trig identity. Determine which angle it is and use its corresponding trig identity.
Trig identity... sin/cos = tangent
The proof of this trig identity relies on the pythagorean trig identity, the most famous trig identity of all time: sin2x + cos2x = 1, or 1 - cos2x = sin2x. 1 + cot2x = csc2x 1 = csc2x - cot2x 1 = 1/sin2x - cos2x/sin2x 1 = (1 - cos2x)/sin2x ...using the pythagorean trig identity... 1 = sin2x/sin2x 1 = 1 So this is less of a proof and more of a verification.
This is to verify your true identity.
The purpose of a login is simply to verify a user's identity.

You need to give more information... you're probably going to use a trig identity though.

An identity document is any document which may be used to verify aspects of a person's personal identity.
I am not familiar with your type of identification, do you mind if I verify your identity with your employer?
