    No problem! Let's go through the questions together:
    1. Find the exact value of sin(π/3).
    - The sine of π/3 (which is 60 degrees) is √3/2.
    2. Solve for x: cos(x) = 0.5, where 0 < x < 2π.
    - To find the angle whose cosine is 0.5, you can use the inverse cosine function (cos⁻¹). So, x = cos⁻¹(0.5).
    - On most calculators, cos⁻¹(0.5) = π/3 or 60 degrees.
    3. If tan(θ) = √3, find the value of θ in radians.
    - To find θ, use the inverse tangent function (tan⁻¹). So, θ = tan⁻¹(√3).
    - On most calculators, tan⁻¹(√3) = π/3 radians or 60 degrees.
    4. Determine the period of the function y = 2sin(3x).
    Pls teach me how to solve with calculator

    Pls ur solutions,pls why didn't u change it to radian but this tym around in degrees

    • @eaglesclass
      @eaglesclass  9 місяців тому +1

      When solving trigonometry, is more recommended you put the calculator in radian mode. Degree mode doesn't work in most cases especially when pi (π) is involved.

      Do you mean if the angles are obtuse instead of acute,? Because the example I used is when the angle is acute.
