Step-by-step explanation: Explanation: Given , (sin75° - cos 75°) So, this can be written as , [sin(45° + 30° ) - cos (45° - 30°)] And we know that the formula of sin(A + B) and cos(A +B), sin(A + B) = sinA cosB + cos A sinB and cos (A + B) = cosAcosB - sinAsinB. This can also be written as the solution 21+ 3i = cos(π/3)+isin(π/3)= eiπ/3 21− 3i = cos(π/3)−isin(π/3) = cos(−π/3)+isin(−π/3)= e−iπ/3 (1+ 3i)9 = 29(eiπ/3)9 (1− 3i)9 = 29(e−iπ/3)9
sine, 75, minus, cosine, 75. You can see the Pythagorean-Thereom relationship clearly if you consider
Click here 👆 to get an answer to your question ️ Rewrite 2 cos 75 degrees sin 75 degrees a double angle identity. sin(2⋅75) sin ( 2 ⋅ 75) Multiply 2 2 by 75 75.
Calculate sin(75)° Determine quadrant: Since 0 ≤ 75 ≤ 90 degrees it is in Quadrant I sin, cos and tan are positive. Calculation: Given, 2 sin 75° cos 75° = sin [2 (75°)] = sin (150°) = sin (90° + 60°) = cos 60° = \(\rm \dfrac 1 2\) Hence, the value of 2 …
2sinx cos x = sin 2x. sin(2⋅75) sin ( 2 ⋅ 75) Multiply 2 2 by 75 75. See that Sin 75° = Cos 15°. The exact value of is . We can rewrite cos (ωt - 75°) using the identity cos (-θ) = cos (θ): Next

It uses functions such as sine, cosine, and tangent to describe the ratios of the sides of a right triangle based on its angles. How to: Given two angles, find the tangent of the sum of the angles. Use inverse trigonometric functions to find the solutions, and check for extraneous solutions. 1/2. sin(30) sin ( 30)
