my friend has pain in the frontal vaginal area she describes it as a jabbing pain that comes every now and then each day

we dont kno what it is any suggestions?

I recently had blonde hair when for some reason i decided to dye it black i hated it so the salon stripped my hair and now the color is a strawberry blonde with more of a red tint. My hair is a little damaged but the hair stylist said it wasnt that bad and that i could get blonde high lights 2 weeks after my hair stripping. I dont mind the color but i want to go back blonde. If i wait a month or 2 and dye my whole head blonde will it work or be bright orange?

I used to dye it with the blondest box from loriel and would do the same again if it doesnt turn my hair orange.

help! thanks!

cos(50)cos(25)-sin(50)sin(25)

I know i have to condense them then expand but not sure how to begin\

help please!

tan(135+120)

do i distribute the tan?

help please!

sin(A + pie) = -sinA

I have no idea where to start...distribute the sin to A and pie?

help please!

So here is the problem:

sin(95)cos(55)+cos(95)sin(55)

i dont understand how you can split up the angles to go along with the unit circle?

help please!

Why is the graph of y=sin(-x) is inverted graph of y=sin(x), where as the graph of y=cos(-x) is the same as y=cos(x)?

thanks!
