WebUse a sum or difference identity to find the exact value of cos (75°) without a calculator. To work this, we look at the 75° to see if it's the sum or difference of any angles from our reference triangles. We see that 75° = 30° + 45°. So: cos (75°) = cos (30° + 45°) We can use the cosine sum identity. cos (α + β) = cos (α)cos (β) – sin (α)sin (β)
