![The product of sin 30 and sin 60 is same as the product of cos 60 degrees tan 30 degrees and cos 30 degrees tan 60 degrees. The product of sin 30 and sin 60 is same as the product of cos 60 degrees tan 30 degrees and cos 30 degrees tan 60 degrees.](https://d138zd1ktt9iqe.cloudfront.net/media/seo_landing_files/q251-1637043189.png)
