Question

What is the result of 1/2 tan theta

Answer 1

Answer:

In mathematics, an "identity" is an equation which is always true. These can be "trivially" true, like "x = x" or usefully true, such as the Pythagorean Theorem's "a2 + b2 = c2" for right triangles. There are loads of trigonometric identities, but the following are the ones you're most likely to see and use.csc(x)=

sin(x)

1

\sin(x) = \dfrac{1}{\csc(x)}sin(x)=

csc(x)

1

\sec(x) = \dfrac{1}{\cos(x)}sec(x)=

cos(x)

1

\cos(x) = \dfrac{1}{\sec(x)}cos(x)=

sec(x)

1

\cot(x) = \dfrac{1}{\tan(x)} = \dfrac{\cos(x)}{\sin(x)}cot(x)=

tan(x)

1

=

sin(x)

cos(x)

\tan(x) = \dfrac{1}{\cot(x)} = \dfrac{\sin(x)}{\cos(x)}tan(x)=

cot(x)

1

=

cos(x)

sin(x)
