First, you need to remember how to obtain the answer.
1) (velocity)*(cosine of the angle)2)(velocity)*(sine of the angle)
Since the plane is traveling 45 degrees below the horizon the angle that we will be using is 180+45=225.
Therefore we will have,
150* cos(225) = -81.31
150*sin(225) = -81.31
*In the unit circle, the coordinates of 225 are -squareroot(2) divided by 2 for both sin and cos, which explains why we have the same answer for both sin and cos.
The answer being negative makes sense since the speed is decreasing due to the fact that the plane is traveling below horizontal.
Based in your question that ask to evaluate the integral of tan^2(x)sec(x), base on my calculation and the use of the integral procedures and formula i came up with a solution that could answer your question and the evaluated answer is <span>tan(x)sec(x)−∫(<span>sec2</span>(x)−1)sec(x)dx</span>

Answer:
Step-by-step explanation:
Let the length of each side of the cube be
x meters.
x3= 123,456
3 square root x3= 3 square root 123,456
x=49.8 m
The length of each side of the cube is
49.8 meters
