Question

Trigonometric equations and trigonometric identities are the same thing. true or flase

Answer 1

wats ur say?

Answer 2

False?

Answer 3

yep thts right

Answer 4

thank you

Answer 5

false because an equation is a "question" in which you are trying to obtain the value of one of its parts, generally noted "x" or "n" (although any letter can work) whereas trigonometic identities are stablished values dependant on the value to which the trigonometric function is applied, and these come from the unit circle.

The unit circle is one of radius 1 in which the trigonometric idents are found based on a right triangle that involves the radius as the hypothenuse, the sine as the vertical side and the cosine as the horizontal side. The values of the sine and cosine are the lenght of these lines on the angle measured, the tangent is the slope of a tangent line traced as perpendicular to the radius.

Answer 6

False;
A trig identity is something that is always true for all values of the angle(s) involved

For example tan A = sin A / cos A is an identity. You do not find A from it because it is true for all A.

Quite often you are asked to prove a trig identity. This means proving something equals something else.

A trig equation, on the other hand, is only true for certain values of the angle(s) involved.

For example tan A = 0.57735 is a trig equation.
It is only true for A = 30° and 210° for solutions between 0° and 360°.

Answer 7

thank you guys!

Answer 8

you're welcome! that's pretty much all the trig you may need :D
