$$Approximatesin46°by‘‘{differentials}^{″}$$$$$$$$Mastermind$$

Commented by mr W last updated on 06/Jun/22

$$\sin 46°=\sin (\frac{\pi }{4}+\frac{\pi }{180})$$$$\approx \sin \frac{\pi }{4}+\cos \frac{\pi }{4}\times \frac{\pi }{180}$$$$=\frac{\sqrt{2}}{2}(1+\frac{\pi }{180})$$$$=\frac{(180+\pi )\sqrt{2}}{360}\approx 0.719$$
