Question

Write all identities you know​

Answer 1

Answer:

Terms in this set (8)

Reciprocal: csc(θ) = csc(θ) = 1/sin(θ)

Reciprocal: sec(θ) = sec(θ) = 1/cos(θ)

Reciprocal: cot(θ) = cot(θ) = 1/tan(θ)

Ratio: tan(θ) = tan(θ) = sin(θ)/cos(θ)

Ratio: cot(θ) = cot(θ) = cos(θ)/sin(θ)

Pythagorean: sin costs = $1. ...

Pythagorean: I tan = get sic. ...

Pythagorean: I cut = crescent rolls.

Answer 2

Answer:

Identity I: (a + b)2 = a2 + 2ab + b2

Identity III: a2 – b2= (a + b)(a – b)

Identity IV: (x + a)(x + b) = x2 + (a + b) x + ab

.Identity V: (a + b + c)2 = a2 + b2 + c2 + 2ab + 2bc + 2ca

.Identity VI: (a + b)3 = a3 + b3 + 3ab (a + b)
