Question

Calcular: R=(sen^2 α+cos^2⁡θ)/3 Si: secθ=8/6 ^ cscα =4/3

Answer 1

Respuesta:

R=3/8

Explicación paso a paso:

Recordar:

Sen α = (Csc α)^(-1) → Sen α = (4/3)^(-1) = 3/4

Cos θ = (Sec θ)^(-1) → Cos θ = (8/6)^(-1) = 6/8

R = [(3/4)² + (6/8)²]/3

R = [9/16 + 36/64]/3

R = [9/16 + 9/16]/3

R = [18/16]/3

R = [9/8]/3

R = 9/24

R = 3/8
