Prove the cofunction Identity using the Addition and Subtraction Formulas. Tan (pi/2 - u) = cot (u) Since tan (pi/2) is undefined, use a Reciprocal Identity, and then use the Substitution Formulas to simplify. Tan (pi/2 - u) = sin/cos (pi/2 - u) = (cos (u)) - (cos (pi/2)) (sin (u))/(sod (pi/2)) (cos (u)) + (sin (pi/2)) (sin (u)) = (cos (u)) - (0) (sin (u))/(0) (cos (u)) + (1) (sin (u)) =/sin (u)

Step-by-step explanation:

We are to prove the cofunction Identity using the Addition and Subtraction Formulas.

From trigonometry identity, , starting from right hand side of the equation, the expression above will become;

Substituting this trigonometry identities into equation 1 we will have;

Since cot(u) = 1/tan(u) = cos(u)/sin(u), hence;

the cat is blue because the probability of extension towards the prefix of the diameter of the circle could only mathematically equal to the sum of the roots of the carrots from   your garden.
