WebThe angle the cable makes with the seabed is 39°. The cable's length is 30 m. And we want to know "d" (the distance down). Start with: sin 39° = opposite/hypotenuse. Include lengths: sin 39° = d/30. Swap sides: d/30 = sin 39°. Use a calculator to find sin 39°: d/30 = 0.6293…. Multiply both sides by 30: d = 0.6293… x 30.

WebYou want to substitute a function in there, so we choose tan (theta) since it is related to sec (theta) by tan^2 (theta) + 1 = sec^2 (theta). So, in order for this substitution to work out okay, you're letting x=a*tan (theta) so that when you write it out, you will end up with a^2+ (a*tan (theta))^2 in your denominator.
WebTo prove this, we'd need to consider values of x approaching 0 from both the positive and the negative side. So, for the sake of simplicity, he cares about the values of x approaching 0 in the interval (-pi/2, pi/2), which approach 0 from both … t-shirt chainsaw man merchWeb6sin (π/2⋅x) = 3. sin (π/2⋅x) = 1/2. From the unit circle, the sine values that equal 1/2 have the solution set x = π/6+2πn, 5π/6+2πn. π/2⋅x = π/6+2πn, 5π/6+2πn. x = 1/3+4n, 5/3+4n. Since we are looking for the 4 smallest positive solutions, we would need to plug in n=0 and n=1: x = 1/3+4 (0), 5/3+4 (0) x = 1/3, 5/3. x = 1/3+4 ... philosophical learningWebAbout Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features NFL Sunday Ticket Press Copyright ... philosophical lawWebUse a calculator to solve the equation sinθ = 0.8 ,where θ is in radians.
