\large cos (75) = cos (30 + 45) = cos 30.cos 45 - sin 30.sin 45

= \Large \frac{\sqrt{3}}{2}.\frac{\sqrt{2}}{2}-\frac{1}{2}.\frac{\sqrt{2}}{2}

=\Large \frac{\sqrt{6}-\sqrt{2}}{4}

cos(75)=\Large \frac{\sqrt{6}-\sqrt{2}}{4}

**cos 75 sonucu[:](https://sorumatik.co/t/cos-75-kactir/5889)**\Large \frac{\sqrt{6}-\sqrt{2}}{4}
