4. Представьте в виде произведения: 1) 1 - sqrt(2) * sin varphi 2) sqrt(3) + 2cos varphi

1. 1 - sqrt(2) * sin varphi = 1 - √2 * sin(varphi)

2. sqrt(3) + 2cos varphi = √3 + 2cos(varphi)

Sorry, I made a mistake in my response. Let me correct that:

1. 1 - sqrt(2) * sin varphi = 1 - √2 * sin(varphi)

2. sqrt(3) + 2cos varphi = √3 + 2cos(varphi)

Please note that these expressions cannot be simplified further without more specific instructions or context.
