tan(61°) = 1.80405 (rounded)
tan(135 degrees) = negative 1.
0.26794919243112270647255365849413
Tangent repeats every 180 degrees, so Tan(180 + a) = tan(a). This site has several useful identities.http://www.mathwords.com/t/trig_identities.htm
1.8807 is. (rounded)
The cotangent function is the reciprocal of the tangent function, so cot(115 degrees) is equivalent to 1/tan(115 degrees). Since tan(115 degrees) is equivalent to -tan(65 degrees) due to the periodicity of the tangent function, cot(115 degrees) simplifies to -tan(65 degrees), which corresponds to option A.
.0089=0.0089=89/10000 Hence as % is (89/10000)*100%=0.89% Thus .0089=0.89%
cot 115 deg = - tan25 deg
Tan 42 degrees = 0.9004
Tan(74 degrees) = 3.487414444.....
tan(11o) = 0.19438 =======
