2.) use a calculator and find to 4 decimal places the value of the trigonometric function using the given identity.
2u = 82°, sin 2u = 2 sin u cos u
a.) 0.9992

b.) 0.9729

c.) 0.9903

d.) 0.0792

e.) 0.9927

thanks for the challenge a is the answer

Step-by-step explanation:

mark brainliest please trying to get ambitious thanks! and heart too 5 stars

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
