(sin(x))^2 and sin(x)^2 and sin^2(x)?
Hello, Are (sin(x))^2 and sin(x)^2 and sin^2(x) the same? Thank you in advance!
What is k in sine functions?
For sine functions, the formula k times pi generally applies to the zeros. But what is k, and what is the difference between it and b?
Calculate angle?
Hello everyone, I have the following question: we have the following dimensions (see photo). We wanted to know if there is any way to calculate the angle in the top right using the lengths and the one right angle? Best regards
Did I calculate the angle sums in the triangle correctly?
Hello, the task: my solution: a) delta dash = 110 degrees, delta = 70 degrees, gamma = 74 degrees b) alpha = 42 degrees, epsilon = 117 degrees
Is this routing correct?
always come out at -6/ pi cos ()
How do I calculate the antiderivative of sin(pi/2x)?
I thought now it is f(x) = sin(pi/2x) then be F(x) = cos(pi/2x) * 1/pi/2 F(x) = 2/pi * cos(pi/2x)
Shift of the sine function in the x direction?
For a sine function, how do I know whether the shift in the x direction was positive or negative? And the solution here is y= 3*sin(π*(x-1)) or 3*sin(π*(x+1)) Thank you for your help in advance
What is the solution for gamma in this triangle?
I got 13.58 degrees for gamma.
Sine and cosine on the unit circle?
Hi, why can you draw the lower triangle of the unit circle like this, instead of using the red line like I did?
Did I assign this correctly?
Here is the translation 1. A scalene triangle with an obtuse angle → Has no equal sides and an angle greater than 90°. 2. An isosceles triangle with three acute angles → Two sides of equal length and all angles less than 90°. 3. An equilateral triangle → All sides are the same length and…
Inequalities sin(x) > – cos(x)?
I come up with the solution pi/4 and 5/4 pi, others with -1/4pi and 3/4pi, I don't know what to do next, can someone help me solve this mathematically.
