btw how do you make the pi symbol on here??j
Find: sin(arccos(3/5))
Find the exact value of csc105 degrees
Simplify: sin (x+y) - sin(x-y)
Prove that: sin2x/cotx = 1-cos2x
Find the exact value of sin(x+ pi/3)
I know thats a lot but any help would be amazing!!! I'm awful at this!!
Hello,
(see where arccos 3/5 lies and conclude about the sign of the sine)
Dunno.. have to find out what csc is...Find the exact value of csc105 degrees
Simplify: sin (x+y) - sin(x-y)
Prove that: sin2x/cotx = 1-cos2x
Use the formulaFind the exact value of sin(x+ pi/3)
