13. Suppose θ is an angle in the standard position whose terminal side is in Quadrant I and sin θ= 84/85. Find the exact values of the five remaining trigonometric functions of θ.

cos θ = 13/85, tan θ = 84/13, sec θ = 85/13, csc θ = 85/84

Step-by-step explanation:

θ in 1st quadrant, all the coordinates are positive

sin θ = 84/85    (for the right angle triangle ABC, A is the right angle and a the hypotenuse, b and c are legs. )

a = 85

b = 84

c = √85² - 84² = 13

cos θ = 13/85, tan θ = 84/13, sec θ = 85/13, csc θ = 85/84

95.03 is the answer. hope this !

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.
