Given that tan a =k and 0<a<π/2 find a) tan(π+a) b) tan(π/2 + a) c) tan(-a)

Instead of walking along two sides of a rectangular field, Fran took a shortcut along the diagonal, thus saving distance equal to half the length of the longer side. Find the length of the...

How many times did the wheel rotat? How many radians did it turn? ps. I need to know how to get the answer, thx!

Determine the acute angle at which y=2x-1 and y=0.5x+2 intersect. Can you please include the process of how to solve the problem? Thank you.

In △ABC, BD is perpendicular to AC. a) Show that the two smaller triangles inside △ABC are similar to each other. b) If BD = x and AD = y, find the ratios of the areas...

A belt 24.75 meters long passes around a 3.5 cm diameter pulley.As the belt makes three complete revolutions in a minute,how many radian does the wheel turn in 2.5 seconds?

equivalent trig expressions

thank you

find cos (a+b) if sin (a) = -3/5 where a is in the fourth quardrant and tan (b) =12/5 where b is in the third quardrant

tanθ = [2x(x+1)]/(2x+1) find Sinθ and Cosθ

of tanA=CotA, then find CosA+SinA

A particle is moving on the perimeter of a circle with radius r=20 with angular speed of π9 radians per second. After completing 4 full rotations, the particle traveled for 5 more seconds and stopped...

Round to the nearest three decimal places. I'm not sure if i should take the derivative and then solve for 0. Using critical values. I'm very confused and my notes are no help.

The answer is 48.5°

I tried solving it using a graphing calculator and by using a triangle with SohCahToa, and I believe the answer is 2/(45^(1/2)) but am told it's wrong. Please help?

In the equation y = kx, k represents the ____________________. A. constant of change B. variability quotient C. scalar D. constant of variation

1.prove each identity sin (q)/1+sin (q)-sin q/1-sin(q)=-2 tan^ 2 (q) 2.(cos^2 q/1-sin q )- (cos^2/1+sin q)

whose solve this problum as early as possible
