what is the reciprocal property for sec X
What is 1/Cos x
100
tan x =
sinx/cosx=secx/cscx
100
sin(-x)=-sin x is this odd or even
odd function
100
2sinx cosx=
sin 2 x
100
cos(a+b)+cos(a-b)=
2cos A cos B
200
what is the reciprocal of sin cos tan
what is csc sec cot
200
cot=
cosx/sinx=cscx/secx
200
cos(-x)=cos x is this odd or even
even
200
cos^2 x-sin^2 x=1-2 sin^2x =
2 cos^2x-1
200
-cos(a+b)+cos(a-b)=
2sin A sin B
300
write Tan x in terms of Sin x and Cos x
What is Sin x/Cos x
300
cos^2 x+sin^2 x=
What is 1
300
tan (-x)=-tanx is this odd or even
odd function
300
2tanx/1-tan^2x=
tan 2x
300
sin(a+b)+sin(a-b)=
2sin A cos B
400
tanxcotx, cosxcecx, sinxcscx are all equal to what
What is 1
400
cot^2 x+1=
What is csc^2x
400
cot(-x)=-cotx is this odd or even
odd function
400
1/2(1-cos2x)=
sin^2x
400
2cos1/2(x+y) cos1/2(x-y)
cos x +cos Y=
500
explain geometrically why the property cos^2x+sin^2x=1 is called a pythagorean property?
cosine and sine are lengths of the legs of a right triangle whose hypotenuse is a radius of a unit circle. the pythangorean theorem then says (cos x)^2+(sin x)^2=1^2
500
1+tan^2x=
csc^2x
