It depends on what information you do have. The answer may not be in radical form but in terms of a trigonometric ratio.
They are different trigonometric ratios!
You can use your trigonometric functions (sine, cosine, and tangent).
The answer depends on what solving is required: do you need to find the area, perimeter, angles, trigonometric rations?
Yes, the sine decreases, and so does the tangent.
11 + 17i is an IMAGINARY number. . Its conjugate is 11 - 17i NB Note the change of sign only.
A conjugate (in the context of math) is, simply put, two numbersseparatedby a sign, in which the sign changes.Example:The conjugate of a+b is a-b. Thepositivebecame negative.For your problem (your sign is missing, so I listed two possibilities):The conjugate of 11+17i is 11-17iThe conjugate of 11-17i is 11+17i

There are three types of trigonometric functions, they are: 1- Plane Trigonometric Functions 2- Inverse Trigonometric Functions and 3- Hyperbolic Trigonometric Functions
The trigonometric formula or the polar coordinate form is x = a + r*cosΦ y = b + r*sinΦ where 0 ≤ Φ < 360 deg.
Use the trigonometric relations and identities.
The sine and cosine are both trigonometric functions. Trigonometric calculations are used in many branches of engineering.
TRIGONOMETRIC FUNCTIONS OF ANY ANGLE
Yes, but it is called a hyberbolic trigonometric function
It depends on what information you do have. The answer may not be in radical form but in terms of a trigonometric ratio.
Use trigonometric identities to simplify the equation so that you have a simple trigonometric term on one side of the equation and a simple value of the other. Then use the appropriate inverse trigonometric or arc function.
