Do the equations sine plus cosine and sine squared plus cosine squared both equal 1?
No, they do not.
Does tangent of x equal cosine divided by sine?
No, it does not.
What is length of the equal sides of an isosceles triangle where the two equal angles are 20 degrees and the third side is 12?
Treat it as being two right angled triangles by halving the base and use the cosine ratio to find its hypotenuse (which will be one of the equal sides) cosine = adjacent/hypotenuse hypotenuse = adjacent/cosine hypotenuse = 6/cosine 20 degrees = 6.385066635 The length of the equal sides = 6.4 units correct to one decimal place.
1 minus 2 cosine squared divided by sine cosine is equal to tangent minus cotangent?
No, it is not. To be correct, the expression requires parenthesis, which are missing.
What is the value of the angle in which the sine and cosine are equal and both negative?
225 degrees
Do the equations sine plus cosine and sine squared plus cosine squared both equal 1?
No, they do not.
Does tangent of x equal cosine divided by sine?
No, it does not.
Are The sine and cosine of acute angles equal?
The sine and cosine of acute angles are equal only for 45° sin45° = cos 45° = 1/sqrt(2) = 0.7071
What is cosine squared theta equal to'?
Cosine squared theta = 1 + Sine squared theta
The trigonometric ratio cosine is equal to?
opposite over adjacent
At what angle measure are the sin and the cosine equal?
45 degree
What does 1 minus cosine theta equal?
There is no easy simplification.
What is length of the equal sides of an isosceles triangle where the two equal angles are 20 degrees and the third side is 12?

When does co secant equal -1?
cosecant(x) = 1/sin(x) = -1sin(x) = -1x = 270 degrees(plus or minus any whole multiple of 360 degrees)
1 minus 2 cosine squared divided by sine cosine is equal to tangent minus cotangent?
No, it is not. To be correct, the expression requires parenthesis, which are missing.
What angle is Sine and cosine equal?
at a 45 degree angle, or pi/4
What is the value of the angle in which the sine and cosine are equal and both negative?
225 degrees
