Question: Determine sin(x + y) when sin(x) = 1/3, -π/2 ≤ x ≤ π/2 and cos(y) = -1/4, π ≤ x ≤ 2π Much appreciated if anyone might be willing to help...

A surveyor notices that the angles of elevation of the top "C" and bottom "D" of a statue placed on a pedestal are 18° and 11° respectively. If his instrument AB is 20m away from...

a pendulum swings back and forth taking 2 seconds to move from the position directly above from point a to the position directly above point b, as shown in the figure below. the distance form a to...

find values for sin θ, cos θ, cot θ, csc θ, sec θ (Include a diagram of a right triangle with hypotenuse in standard position)

A point on an industrial flywheel experiences a motion described by the function h(t)=13cos(pi/0.35)t + 15. What is the general solution for the time it takes to reach maximum height...

The water at a local beach has an average depth of one meter at low tide and an average depth at high tide of 8m. One cycle of the tides takes approximately 12 hours. This periodic motion can be modelled...

The depth of water in a certain area can be estimated by using this equation: h(t)=-4.3cos(pi/6.35(t+1.6))+8.4 A boat requires a depth of 7.2 m to ensure safe...

Suppose a sales can be modelled by the equation; S=200+200cos[pi/6(t+2)] where t is time in months with t=0 corresponding to January for what month are sales...

If csc(α) = 3, where 0 < α < π/2, and β is a Quadrant II angle with tan(β) = −7, find cos(α+β) And there are others that I'm supposed to find, such as sin(α+β),...

options given g(x) = √(x2-1) g(x) = √(1-x2) g(x) = (π/2) +x g(x) = (π/2) - x g(x) = tanx I tried doing it but cos^-1(sinx) isn't possible to do with what i know

A sine function has a maximum value of -5, a minimum value of -29, and consecutive minimum values when x= -π/5 and x= (4π)/15. Determine the phase shift

A boat sails on a bearing of 75° for 128miles and then turns and sails 203miles on a bearing of 191°. Find the distance of the boat from its starting point. I am unsure how to solve...

solve the equation for the solutions over the interval [0 degrees, 360 degrees) 6sec2xtanx=12tanx I am unsure of where to begin.

cos(3theta)=-1 solve for exact solutions over the interval [0,360 degrees] I am having trouble finding a place to start.

I am getting stuck at 7 plus or minus sqrt 309 / 26 13sin^2x-7sinx=5 solve for interval [0,360degrees]

Plz help me solve this sum, I will really appreciate it.
