Refer to the table below if needed.

Second Quadrant Third Quadrant Fourth Quadrant
sin(180 -) = sin sin(180 +) = - sin sin(360 -) = - sin
cos(180 -) = - cos cos(180 +) = - cos cos(360 -) = cos
tan(180 -) = - tan tan(180 +) = tan tan(360 -) = - tan
cot(180 -) = - cot cot(180 +) = cot cot(360 -) = - cot
sec(180 -) = - sec sec(180 +) = - sec sec(360 -) = sec
csc(180 -) = csc csc(180 +) = - csc csc(360 -) = - csc
Evaluate, using the tables if necessary.

Answer:

12

Step-by-step explanation:

y=c that make 0 and then i mulitply -1 to -12

then i did the opposite for 360 time -12 that 700 and then i devided and got 12

The resulting value for the given sum of trignometry identity is -2

Trigonometry identity are written in tems of sine, cosine and tangent

According to the trigonometry identity

sec theta = 1/costheta

cot theta = 1/tantheta

Given the trigonometry expression

sec 180 + sin 270 - tan 180 + cot 270

This can also be written as;

1/cos180 + sin270 - tan 180 + 1/tan270

= -1/cos0 + (-sin90) - tan0 +1/tan90

= -1 - 1 - 0 +1/∞

= -1 -1 + 0
= -2

Hence the resulting value for the given sum of trignometry identity is -2
