Answer:
The equivalent expression is cosec2x
option B
Step-by-step explanation:
The correct question is ;
which expression is equivalent to sec2xcot2x?
Solution
Mathematically;
sec2x = 1/cos2x
cot2x = 1/tan2x
so we have
1/cos2x * 1/tan2x
recall that the product of tan and cos is sin
from the formula;
tan = sin/cos
so we have our final answer as;
1/sin2x
Kindly recall that ;
sin = 1/cosec
so therefore;
1/sin2x = csc2x
A because 1-10 would be -9 and she was a meter above so positive but they descended 10 meters no negitve
Answer:
Step-by-step explanation:
Tan-1(19.0811) = 86.999994
That's about as close to 87 as you can get with 6 places of accuracy. The trick is knowing how to get the inverse tangent (tan-1(x) ), or maybe it is just knowing that you have to get it. The inverse tan starts with a decimal number that comes from the tangent definition Tan(theta) = opposite / adjacent.
So what you are starting with is the ratio for the Tangent and you are trying to find the angle theta. In this case, it is 87.
