Sandra knows the pythagorean identity sin 2 ⁡ θ + cos 2 ⁡ θ = 1 . if she is told that 0 ≤ θ ≤ π 2 and cos ⁡ θ = 5 12, what will she get when she correctly calculates tan ⁡ θ ?

Step-by-step explanation:

We have been given that Sandra knows the Pythagorean identity . She is told that and .

First of all, we will find value of sine theta using the given identity.

Therefore, .

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5

is only a line? i think so
