When you subtract theta from 180 ( if theta is between 90 degrees and 180 degrees) you will get the reference angle of theta; the results of sine theta and sine of its reference angle will be the same and only the sign will be different depends on which quadrant the angle is located. Ex. 150 degrees' reference angle will be 30 degrees (180-150) sin150=1/2 (2nd quadrant); sin30=1/2 (1st quadrant) 1st quadrant: all trig functions are positive 2nd: sine and csc are positive 3rd: tangent and cot are positive 4th: cosine and secant are positive

Every multiple of 180 degrees, beginning with zero.

The trig identaty of cot(x) is cos(x)/sin(x) so then if we want to evaluate cot (68) deg. we just plug into the identady. so cos(68)/sin(68)=.404

one way to do it is to first draw a rectangle around the octagon then multiply length by width then subtract the area of the four triangles out side the octagon from your total answer. OR You can use the formula A= 2 s2 cot(π/h) π is supposed to be pi s2 is supposed to be s squared Cot is an abbreviation for cotangent

It is -sqrt(1 + cot^2 theta)

Yes, it is.

It depends if 1 plus tan theta is divided or multiplied by 1 minus tan theta.

tan2(theta) + 5*tan(theta) = 0 => tan(theta)*[tan(theta) + 5] = 0=> tan(theta) = 0 or tan(theta) = -5If tan(theta) = 0 then tan(theta) + cot(theta) is not defined.If tan(theta) = -5 then tan(theta) + cot(theta) = -5 - 1/5 = -5.2

-2(cot2theta)

cosec(q)*cot(q)*cos(q) = 1/sin(q)*cot(q)*cos(q) = cot2(q)

Until an "equals" sign shows up somewhere in the expression, there's nothing to prove.

For a start, try converting everything to sines and cosines.

cot theta=tan(90-tetha)

whats the big doubt,cot/tan+1= 1+1= 2
