Answer:
Csc(0)
Step-by-step explanation:
in trigonometry, the basic functions are Sine , Cosine and Tangent. Other functions such as Cotangent, Secant and Co secant are derivatives of these 3.
We know that
Csc Ф = 1/Sin Ф
Cot Ф = 1/tan Ф = cos Ф/ sin Ф
hence cos(0) csc(0)/sin(0)cot(0)
= cos Ф * 1/sin Ф ÷ sin Ф *cos Ф / sin Ф
= cos Ф/sin Ф * 1/ cos Ф
= 1/ sin Ф
= Csc Ф
Answer:
7
Step-by-step explanation:
3x - y = 1
2x + 2y = 14
x = 2
y = 5
x + y = 2 + 5 = 7
