$\large\mathfrak\pink{\implies sin^2\: a + cos^2a = 1 }$

$\large\mathfrak\blue{\implies sec^2\: a - tan^2a = 1 }$

$\large\mathfrak\orange{\implies cosec^2\: a - cot^2a = 1 }$

Answer 2

Step-by-step explanation:

Basic and Pythagorean Identities

$\bf \green{(x) = \dfrac{1}{\sin(x)}}$

$\sf\purple{\sin(x) = \dfrac{1}{\csc(x)}} \\ \sf{sec(x) = \dfrac{1}{\cos(x)} }\\ </p><p></p><p> \sf \red{\cos(x) = \dfrac{1}{\sec(x)}} \\ \:$

 

sin2(t) + cos2(t) = 1

tan2(t) + 1 = sec2(t)

1 + cot2(t) = csc2(t)

sin(–t) = –sin(t)

cos(–t) = cos(t)

tan(–t) = –tan(t)
