Basic
Name the two quotient identities
What is tanx & cotx?
If tan2x+1=sec2x, then sec2x-tan2x=?
What is 1?
These two even-odd identities remain positive
What is cos(-x) & sec(-x)?
cosx equals this cofunction identity
What is sin(3.14/2-x)?
cscx multipled by sinx & tanx divided by cotx equals this
What is tan2x?
cscx, secx, cotx are called these identities
What are reciprocal identities?
If sec2x-tan2x=1 then sec2x-tan2x=?
What is cos2x+sin2x?
If the identity remains the same when reflected across the y-axis, then the identity is this
csc(pie/2 radians-x) equals this trigonometric function
What is secx?
The answer to sinx(cscx-sinx)
What is cos2x?
If the three main trigonometric identities (tanx, sinx, & cosx) are divide by their reciprocal identities (cscx, secx, & cotx), then the answer will be
What is the trigonometric identity squared?
To reduce an expression into a single trig expression, you need to do this first.
What is write everything in sin & cos?
If the identity remains the same when reflected across the x-axis, then the identity is this
What is the identity is odd?
A cofunction identities purpose is to establish the relationship between these two things
What is trigonometric functions & complementary angles?
tanx/cotx + sin(pie/2 radians-x) multiplied by secx equals this.
What is sec2x?
Name the difference between simplifying verifying, and solving basic trigonometric identities
What is simplify means an expression, verify means an equation, and solving means an answer?
To prove sin2x+ cos2x=1. You must divided by this variable in the equation, x2 + y2= r2
What is divide by r2?
Name three of the negative/ odd identities
What are sin(-x), csc(-x), tan (-x), cot (-x)?
tanx equals cot(pie/2 radians-x) & cotx equals this
What is tan(pie/2 radians-x)?
tanx/cotx + sin(-x) multiplied by cscx
What is tan2x-1?
The 2 of a basic trigonometric identity goes where?
What is behind the trigonometric identity & before the variable?
To prove that cot2x + 1=csc2x, you must divide the equation x2+y2=r2 by this variable
What is y2?
We use even-odd identities when the angles are this
What is opposite & different measures?
These two-cofunction identities equal sin & it's reciprocal identity
What is cos(pie/2 radians-x) & sec(pie/2 radians-x)?
cos(-x)/sin(pie/2 radians-x) + sin(-x)/cscx
What is cos2x?
